" in scope time, all adopt this kind of series system to realize effective input of controller, " be more than or equal to the nominal charging voltage value of energy storage component
be less than or equal to m
*the nominal charging voltage value of energy storage component
" in scope time in parallel, voltage is constant; Or the DC terminal voltage of single cover winding in " being more than or equal to nominal charging voltage value/2 of energy storage component; be less than the nominal charging voltage value of energy storage component " scope time, all adopt this kind of series system to realize effective input of controller, " be more than or equal to the nominal charging voltage value of energy storage component, be less than or equal to m
*the nominal charging voltage value of energy storage component " time shunt voltage constant.What therefore sent by cover winding generating end single after this circuit is positioned at " the nominal charging voltage value of energy storage component
the nominal charging voltage value of energy storage component
" voltage in interval is all effective voltage, wide pressure scope improves 2 times than before, takes full advantage of power generation energy resource, improves the utilance of generator.
With a specific embodiment, the present invention is described below, illustrates as example using single cover winding generating terminal voltage.As the nominal charging voltage value 29.6VDC of energy storage component, charging manager itself has 3 times wide pressure process range, i.e. m=3, then the output voltage of corresponding single cover winding generating end is all effective voltage at 21VAC-63VAC, can charge through charging manager treatment and supplied energy storage component.The voltage exported as simplex winding is 10.5VAC, if without this circuit, then this voltage is dead voltage, and after foregoing circuit series connection, voltage is upgraded to original 2 times and becomes 21VAC, effectively; The voltage exported as simplex winding is 12VAC, if without this circuit, then this voltage is dead voltage, and after foregoing circuit series connection, voltage is upgraded to original 2 times and becomes 24VAC, effectively; The voltage exported as simplex winding is 15VAC, if without this circuit, then this voltage is dead voltage, and after foregoing circuit series connection, voltage is upgraded to original 2 times and becomes 30VAC, effectively; The voltage exported as simplex winding is 20VAC, if without this circuit, then this voltage is dead voltage, and after foregoing circuit series connection, voltage is upgraded to original 2 times and becomes 40VAC, effectively,
And the voltage of the 21VAC-63VAC sent for generator simplex winding is originally just within the scope of effective voltage, without the need to boosting, therefore now namely many cover winding parallels directly use the output voltage of simplex winding, when voltage as simplex winding output is 22VAC, now above-mentioned double winding parallel connection keeps magnitude of voltage constant, in like manner, as simplex winding export voltage be 30VAC time, 40VAC time, during 50VAC, the parallel connection of above-mentioned double winding during 60VAC, is all allowed to keep the magnitude of voltage exporting to charging manager to be exactly the voltage that generator list cover winding exports.
Visible, simplex winding generating holds the voltage of the 10.5VAC-63VAC sent all effective, effective voltage scope is made to become 10.5VAC-63VAC by original 21VAC-63VAC, wide pressure scope becomes 6 times, the basis of 3 times improves 2 times again, the voltage of the disabled 10.5VAC ~ 21VAC section of the script that generator windings is sent also can be energy storage component charging, takes full advantage of power generation energy resource, improves the utilance of generator.Boost during series connection, electric current is constant, and time in parallel, voltage is constant, and electric current increases.
Above-described embodiment describes the connection of double winding, also can be 3 covers, 4 cover windings, during many cover windings, connect by above-described mode between every double winding, because this is that those skilled in the art are easy to expect according to above-mentioned annexation, therefore do not detail at this.The words of 3 cover windings, the output voltage of 7VAC-63VAC is all effective, the words of 4 cover windings, the output voltage of 5.25VAC-63VAC is all effective, often increases a set of winding, and wide pressure scope just expansion is twice, prevent the waste of the energy, the utilance of generator is higher, with during above-mentioned double winding in like manner, therefore not repeat them here.
For the situation of two covers, two-phase phase place symmetric winding, identical with above-mentioned three-phase windings, circuit is as Fig. 5, one end of first set winding RZ1 ' is as output, short circuit between the phase line of one end of the second cover winding RZ2 ', form zero-potential point (electric generator structure processes), the other end of the second cover winding RZ2 ' is connected to form series loop by the second relay B ' of double-pole single-throw (D.P.S.T.) and one end of first set winding RZ1 ', is connected to output simultaneously forms shunt circuit by the first relay A ' of dpdt double-pole double-throw (DPDT).Output connects the first bridge rectifier be made up of diode D1 '-D4 ', and the output of the first bridge rectifier connects inductance L 1 ', and inductance E1 ' is in parallel with the first bridge rectifier.Charging manager U1 connects the energy storage components such as storage battery.Above-mentioned inductance and electric capacity are all filter actions, and principle is identical with above-mentioned three-phase windings, therefore does not repeat.
For when exceeding the treatable maximum process magnitude of voltage of charging manager, this part power supply is inactive power sources, charging manager cannot process, energy storage component cannot be supplied, the words that charging manager internal circuit accumulates certainly will damage the components and parts of charging manager, and therefore described charging manager also comprises a magnitude of voltage of working as the list cover winding generating end that charging manager detects and is greater than the treatable maximum process magnitude of voltage of described charging manager
or single cover direct current terminal voltage value is greater than m
*the unloading control device of off-load is carried out during the nominal charging voltage value of energy storage component; described off-load is undertaken by off-load device; the electric current of excessive magnitude of voltage is laid down, prevents from damaging charging manager and energy storage component, protect the life-span of charging manager and energy storage component.
By Blast Furnace Top Gas Recovery Turbine Unit (TRT) as solar energy, when body-building device or wind-force are energy storage component charging, because these energy sources are all unstable, therefore little time large when voltage is understood, therefore can not once detect that change in voltage just switches, and row again will to be detected after the situation of voltage fully switch, in order to avoid occur that switching device does not stop the problem switched, and causes potential safety hazard.

e2 represents the nominal charging voltage value of energy storage component
e3 represents m
*the nominal charging voltage value of energy storage component
be less than e1, the voltage being greater than e3 is all dead voltage.
