Die gleichgerichtete Spannung ist durch einen Kondensator 52 geglättet. In diesem Fall wird ein Schaltnetzteil nach dem Flyback-Prinzip benutzt. Ein Schalt-IC 53 schaltet die Spannung an einem Transformator 56 an und aus. Wenn die Spannung abgeschaltet wird, fließt kein Strom mehr durch den Transformator 56 und dies bewirkt eine induzierte Spannung in der Primärwindung des Transformators 56. Eine Zenerdiode 54 und eine Diode 55 haben den Zweck, diese induzierte Spannung zu begrenzen, und damit zu verhindern, dass die Spannung auf dem Schalt-IC 53 zu hoch wird.5 shows a rectifier 51 in the circuit diagram of a mains plug, which provides a direct voltage that can be switched by means of radio or Bluetooth signals, which is connected to a main voltage 50 and whose maximum current is protected by a fuse 71. The rectified voltage is smoothed by a capacitor 52. In this case, a switching power supply based on the flyback principle is used. A switching IC 53 switches the voltage on a transformer 56 on and off. When the voltage is switched off, current no longer flows through the transformer 56 and this causes an induced voltage in the primary winding of the transformer 56. A zener diode 54 and a diode 55 have the purpose of limiting this induced voltage and thus to prevent that the voltage on the switching IC 53 becomes too high.
Die Spannung einer der Sekundärwicklungen desTransformators 56 wird gleichgerichtet durch eine Diode 57 und geglättet durch einen Kondensator 58. Diese Gleichspannung wird genutzt, um ein mit einer Antenne 93 ausgestattetes Funk- oder Bluetooth- Modul 59 und einen Regel-IC 60 mit Spannung zu versorgen. Diese Spannung ist auch verknüpft mit dem Schalt-IC 53 mittels eines Optokopplers 61 , einer Zenerdiode 62 und einem Widerstand 63.The voltage of one of the secondary windings of the transformer 56 is rectified by a diode 57 and smoothed by a capacitor 58.

Die gleichgerichtete Spannung ist mittels eines Kon- densators 74 geglättet. In diesem Fall wird ein Schaltnetzteil nach dem Flyback-Prinzip genutzt. Ein Schalt-IC 75 schaltet die Spannung eines Transformators 78 an und aus. Wenn die Spannung ausgeschaltet wird, kann kein elektrischer Strom mehr durch den Transformator 78 fließen, wodurch eine induzierte Spannung in der Primärwindung des Transformators 78 erzeugt wird.

A rectifier 73 is connected to a voltage supply 72, its maximum current being limited by a fuse 94. The rectified voltage is determined by means of a capacitor 74 smoothed. In this case, a switching power supply based on the flyback principle is used. A switching IC 75 turns the voltage of a transformer 78 on and off. When the voltage is turned off, electrical current can no longer flow through transformer 78, creating an induced voltage in the primary winding of transformer 78. A zener diode 76 and a diode 77 have the purpose of limiting this induced voltage and thereby preventing the voltage on the switching IC 75 from becoming too high.
Die Spannung einer der Sekundärwicklungen des Transformators 78 ist gleichgerichtet durch eine Diode 79 und geglättet durch einen Kondensator 80. Diese Gleichspannung wird genutzt, um ein Funk- oder Bluetooth-Modul 81 und einen Regel-IC 82 mit Spannung zu versorgen.

The control IC 82 switches the transistor 87 on or off by means of signals which the Bluetooth module 81 receives via its antenna 93 and forwards to the control IC 82 which switches the transistor 87 on or off.
Die nach dem Transistor 87 anliegende Spannung wird weiterhin durch einen Kondensator 88 geglättet und mittels einer Spule 89 und einem weiteren Kondensator 90 gefiltert.The voltage present after the transistor 87 is further smoothed by a capacitor 88 and filtered by means of a coil 89 and a further capacitor 90.

Der Schalt-IC 98 schaltet die Spannung an einem Transformator 101 an und aus. Wenn die Spannung ausgeschaltet wird, fließt kein elektrischer Strom mehr durch den Transformator 101 , so dass eine induzierte Spannung in der Primär- Wicklung des Transformators 101 induziert wird. Eine Zenerdiode 99 und eine Diode 100 sind vorgesehen, um diese Spannung zu begrenzen, und damit zu verhindern, dass die Spannung auf einem Schalt-IC 98 zu hoch wird.7 shows the switching function of a mains plug with a fixed DC voltage, by means of which a maximum current can be monitored by means of radio or Bluetooth signals.

Diese Spannung ist ebenso verknüpft mit dem Schalt-IC 98 mittels eines Optokopplers 106, einer Zenerdiode 107 und eines Widerstandes 108.The voltage of one of the secondary turns of the transformer 101 is rectified by means of a diode 102 and smoothed by means of a capacitor 103. This DC voltage is used to supply a radio or Bluetooth module 104 and a control IC 105 with voltage. This voltage is also linked to the switching IC 98 by means of an optocoupler 106, a zener diode 107 and a resistor 108.
Die andere Sekundärwindung ist ebenso gleichgerichtet mittels einer Diode 109, jedoch besteht in diesem Fall die Möglichkeit, die Spannung durch einen Transistor 110 weiterzuleiten oder nicht. Die nach dem Transistor 110 erhaltene Spannung ist weiterhin geglättet mittels eines Kondensators 111 und gefiltert mittels einer Spule 112 und eines weiteren Kondensators 113. Die gefilterte Spannung ist dann verbunden mit einem Messkreis 114, wo der elektrische Strom gemessen wird. Wenn der elektrische Strom das festgelegte Maximalniveau überschreitet, schaltet der Regel-IC 105 eine Ausgangsspannung 115 aus oder reduziert diese, wodurch der elektrische Strom zumindest veringert wird. Das Bluetooth-Modul 104 erhält über dessen Antenne 93 Signale, welche Maximalwerte des elektrischen Stroms enthalten und leitet diese an den Regel- IC 105 weiter.The other secondary turn is also rectified by means of a diode 109, but in this case it is possible to pass on the voltage through a transistor 110 or not. The voltage obtained after transistor 110 is also smoothed by means of a capacitor 111 and filtered by means of a coil 112 and a further capacitor 113. The filtered voltage is then connected to a measuring circuit 114, where the electrical current is measured. When the electric current exceeds the predetermined maximum level, the control IC 105 turns off or reduces an output voltage 115, thereby at least reducing the electric current. The Bluetooth module 104 receives signals via its antenna 93 which contain maximum values of the electrical current and forwards them to the control IC 105.
Fig. 8 zeigt die Schaltfunktion eines Netzsteckers, durch welchen eine Gleichspannung und der Maximalstrom mittels Funk- oder Bluetooth-Signalen überwachbar ist. An eine Hauptspannung 118 ist ein Gleichrichter 119 angeschlossen, dessen Maximalstrom mittels einer Sicherung 140 geschützt ist. Die gleichgerichtete Spannung wird durch einen Kondensator 120 geglättet. In diesem Fall wird ein Schaltnetzteil nach dem Fly- back-Prinzip genutzt. Ein Schalt-IC 121 schaltet die Spannung an einem Transformator 124 ein und aus. Wenn die Spannung ausgeschaltet wird, fließt kein elektrischer Strom mehr durch den Transformator 124, wodurch eine induzierte Spannung in der Primärwindung des Transformators 124 erzeugt wird. Eine Zenerdiode 122 und eine Diode 123 haben den Zweck, diese induzierte Spannung zu begrenzen, und damit die Spannung auf dem Schalt-IC 121 zu begrenzen.8 shows the switching function of a mains plug, by means of which a direct voltage and the maximum current can be monitored by means of radio or Bluetooth signals. A rectifier 119, whose maximum current is protected by a fuse 140, is connected to a main voltage 118. The rectified voltage is smoothed by a capacitor 120. In this case, a switching power supply according to the fly back principle used. A switching IC 121 switches the voltage on a transformer 124 on and off. When the voltage is turned off, electrical current no longer flows through transformer 124, creating an induced voltage in the primary winding of transformer 124. A zener diode 122 and a diode 123 have the purpose of limiting this induced voltage and thus limiting the voltage on the switching IC 121.
Die Spannung einer der Sekundärwindungen des transformators 124 wird durch eine Diode 125 gleichgerichtet und durch einen Kondensator 126 geglättet. Diese Gleich- Spannung wird genutzt, um ein Bluetooth-Modul 127 und einen Regel-IC 128 mit Spannung zu versorgen. Diese Spannung ist ebenso verknüpft mit dem Schalt-IC 121 mittels eines Optokopplers 129, einer Zenerdiode 130 und eines Widerstandes 131.The voltage of one of the secondary windings of the transformer 124 is rectified by a diode 125 and smoothed by a capacitor 126. This DC voltage is used to supply a Bluetooth module 127 and a control IC 128 with voltage. This voltage is also linked to the switching IC 121 by means of an optocoupler 129, a zener diode 130 and a resistor 131.
Die andere Sekundärwicklung ist ebenso gleichgerichtet mittels einer Diode 132, wobei jedoch in diesem Fall die Möglichkeit besteht, die Spannung über einen Transistor 133 weiterzuleiten oder nicht. Die nach dem Transistor 133 erhaltene Spannung wird weiterhin durch einen Kondensator 134 gemittelt und durch eine Spule 135 und einen weiteren Kondensator 136 gefiltert. Die gefilterte Spannung ist dann verbunden mit einem Messkreis 137, in welchem sowohl die Spannung als auch der elektrische Strom gemessen wird. Auf Basis dieser Messungen und der spezifizierten Werte schaltet der Regel-IC die Spannung an oder aus. Das Funk- oder Bluetooth-Modul 127 erhält über dessen Antenne 139 Signale, welche die Werte der Spannung und des elektrischen Stroms enthalten, und leitet diese Spezifikationen an den Regel-IC 128 weiter. Eine geregelte Ausgangsspannung 138 liegt nach dem Messkreis 137 an.The other secondary winding is also rectified by means of a diode 132, but in this case it is possible to pass on the voltage via a transistor 133 or not. The voltage obtained after transistor 133 is further averaged by a capacitor 134 and filtered by a coil 135 and a further capacitor 136. The filtered voltage is then connected to a measuring circuit 137, in which both the voltage and the electrical current are measured. Based on these measurements and the specified values, the control IC switches the voltage on or off. The radio or Bluetooth module 127 receives signals containing the values of the voltage and the electric current via its antenna 139 and forwards these specifications to the control IC 128. A regulated output voltage 138 is present after the measuring circuit 137.
Fig. 9 zeigt die Schaltfunktion eines Netzsteckers, durch welchen eine Gleichspannung und der Maximalstrom mittels Funk- oder Bluetooth-Signalen regelbar sind, um eine Batterie in einem an den Netzstecker angeschlossenen Gerät optimal zu laden. Mit einer Hauptspannung 141 ist ein Gleichrichter 142 verbunden, dessen Maximalstrom durch eine Sicherung 166 geschützt ist. Die gleichgerichtete Spannung ist mittels eines Kondensators 143 geglättet. In diesem Fall wird ein Schaltnetzteil nach dem Flyback- Prinzip genutzt. Der Schalt-IC 144 schaltet die Spannung eines Transformators 147 an und aus. Wenn die Spannung ausgeschaltet wird, fließt kein Strom mehr durch den Transformator 147, so dass in der Primärwindung des Transformators 147 eine induzierte Spannung erzeugt wird. Eine Zenerdiode 145 und eine Diode 146 haben den Zweck, diese induzierte Spannung zu begrenzen, und damit zu verhindern, dass die s Spannung auf dem Schalt-IC 144 zu hoch wird.FIG. 9 shows the switching function of a mains plug, by means of which a direct voltage and the maximum current can be regulated by means of radio or Bluetooth signals in order to optimally charge a battery in a device connected to the mains plug. A rectifier 142 is connected to a main voltage 141, the maximum current of which is protected by a fuse 166. The rectified voltage is smoothed by means of a capacitor 143. In this case, a switching power supply based on the flyback principle is used. The switching IC 144 turns on the voltage of a transformer 147 and from. When the voltage is switched off, current no longer flows through the transformer 147, so that an induced voltage is generated in the primary winding of the transformer 147. A zener diode 145 and a diode 146 have the purpose of limiting this induced voltage and thereby preventing the voltage on the switching IC 144 from becoming too high.
Die Spannung einer der Sekundärwicklungen des Transformators 147 wird gleichgerichtet durch eine Diode 148 und geglättet durch einen Kondensator 149. Diese Gleichspannung wird genutzt zur Spannungsversorgung eines Funk- oder Bluetooth-Moduls 0 150 und eines Regel-IC's 151. Diese Spannung ist ebenso verknüpft mit dem Schalt-IC 144 mittels eines Optokopplers 152, einer Zenerdiode 153 und eines Widerstandes 154.The voltage of one of the secondary windings of the transformer 147 is rectified by a diode 148 and smoothed by a capacitor 149. This DC voltage is used to supply a radio or Bluetooth module 0 150 and a control IC 151.
