Power transfer module 104, Main Function is the direct current alternating current of 220V being transformed to 12V through LNK304 voltage stabilizing chip, again through corresponding low-pressure linear pressurizer (Low Dropout Regulator, LDO) for system provides the direct voltage of 5V and 3.3V.
Fig. 2 is power transfer module 104AC/DC change-over circuit figure, in AC/DC change-over circuit, the alternating voltage first rectifying and wave-filtering after the filter circuit that the first diode D3 (4007), the first electric capacity C8 (407uF/400V) and the first resistance R4 (10OHM/1W) form of AC end input; In this AC/DC change-over circuit, in order to stabilizing output current, LinkSwitch-TN ON/OFF control mode will be used, the efficiency that ratio capacitance buck linear stabilized power supply is higher can not only be reached like this, and can power factor be improved, the basis of reduction interference can also reduce the power loss from reduction voltage circuit; In this circuit, the selection of the second diode D4 (1000V 1A) of afterflow can be determined by the working method of chip LNK304, when the mode of operation of this chip is continuous mode, the resume speed of the second diode D4 quickly, only needs lower than 35ns; When the mode of operation of this chip is non-continuous mode, the second diode D4 is then equivalent to a supper-fast diode, and resume speed is a little slower a little, but also only needs the time interval close to 75ns.Inductance L 2 (1mH) is a ready-made inductance element with suitable effective current (RMS electric current) grade, thus can play the effect of protective circuit to a certain extent.The major function of the second electric capacity C3 (100uF/16V) is deboost ripple, consider the protection to overload and short circuit, be used for reaching this protection object by the second resistance R1 (12K) and the 3rd resistance R3 (2K) dividing potential drop in this circuit, during normal work, the voltage of the FB pin of LNK304 is basically stable at 1.65V, when circuit breaks down, such as minusg or send out short circuit time, will significant change be there is in FB pin voltage, and then make the electric current flowing to feedback pin FB increase above 49 μ A, metal-oxide half field effect transistor (Metal-Oxide-Semiconductor Field-Effect Transistor in LNK304, the switch of MOSFET is prohibited at next cycle, make it enter into autoboot and move state.
Power transfer module 104, after realizing the transformation of AC-to DC, also need the direct voltage of 12V to be converted to 5V and 3.3V two kinds of direct voltages, for the power collection module 105 in charging smart jack 1, radio-frequency identification reader/writer 107, first ZigBee module 106 and controller 109 are powered.As shown in Figure 3, realized the voltage stabilizing of 5V voltage by 78L05 DC voltage-stabilizing pipe, then export the voltage of 3.3V through HT7533 linear voltage stabilization pipe, use suitable capacitor filter to guarantee the stable of voltage simultaneously.
Power collection module 105, gathers the realtime power value on charging smart jack 1, and sends the data to controller 109.In the present system, power collection module 105 take CS7760 as core, and it, while guarantee low cost, small size, has high accuracy, the feature of high reliability.CS7760 adopts high-precision adc (Analog to Digital, and Digital Signal Processing (Digital Signal Processing ADC), DSP) technology combined, the reference voltage of Embedded high stable, very low to the susceptibility of the external disturbance such as temperature, ripple, under severe external condition, also can maintain the high accuracy of measuring and stability.
Fig. 4 is the interface connection layout between CS7760 and electric current and voltage Acquisition Circuit and controller; When power collecting, V1P and V2P of CS7760 accesses the voltage and current signal through signal conversion respectively, V1N and V2N accesses the analog signal after circuit filtering after filtering, forms differential signal with V1P and V2P; Then by ac voltage signal and ac current signal digitlization, acquisition principle as shown in Figure 5, after ac voltage signal and ac current signal digitlization, by (the High Pass Filter of high pass filter in sheet, HPF) deliver to internal multiplier 501 after 500 high-pass filterings to be directly multiplied and to obtain instantaneous active power, be converted to frequency signal by a number frequency transducer (being also voltage to frequency converter) 503 and export from CF pin again after low pass filter (Low Pass Filter, LPF) 502 low-pass filtering.
As shown in Figure 4 and Figure 5, illustrate in power collection module 105, the frequency signal exported from CF pin and the relation of power consumption equipment performance number.
For household electricity voltage 220V, what suppose that power collection module 105 collects is sinusoidal voltage and sinusoidal current, then the calculating of instantaneous voltage and current value is as shown in formula (1) and (2):
Wherein U is the effective value of input voltage, and I is the effective value of input current, and ω is frequency, then its instantaneous power can calculate according to formula (3):
P(t)＝I(t).V(t)＝I×U×(1+cos(2ωt)) (3)
The output frequency of corresponding CS776 can be calculated by formula (4):
Wherein, V
1, rmsrepresent the effective value (RMS) of current input signal, V
1, rms=(V1P-V1N)
rms;
V
2, rmsrepresent the effective value (RMS) of voltage input signal, V
2, rms=(V2P-V2N)
rms;
V
refrepresent the reference voltage of chip;
A represents the PGA gain of electric current;
F
brepresent reference frequency, (as shown in Figure 4) is set by SCF, S0, S1;
C is constant, arranges relevant (as shown in Figure 4) with SCF, S0, S1.
