Pin 3.The two-way PWM wave producers use SG3525.The drive module uses FAN7390.The pfc controller uses
UC3842.The diode D3 is voltage-regulator diode.
The present invention operation principle be：Referring to Fig. 1, exchange AC first becomes 380V's after EMI is filtered, APFC is corrected
Direct current, then through high-frequency inversion semi-bridge alternation, high frequency transformer and current rectifying and wave filtering circuit, ensure that output current voltage meets to store
The charge requirement of battery pack, output sampling module are produced by the sampling feedback to accumulator battery voltage, current signal by SG3525
MOSFET make-and-break time controls charging current and charging voltage in raw two-way PWM ripples control high-frequency inversion half-bridge, and system is also
Display monitoring can be carried out to the electric current in charging process, voltage, temperature parameter with a discharge and recharge real-time display module.
In APFC circuits, L is PFC inductance, and D1 is PFC diodes, and C1 is civil power filter capacitor, and VT is PFC power tubes, R0
For mains current sampling resistor, the mains current sampled voltage of PFC control circuit input is negative value, and R1, R2 adopt for DC voltage
Sample resistance, PFC control circuit pass through the analysis to mains input voltage, VD and circuital current sampled value, output
Control signal, the dutycycle of PFC power tubes is controlled, so as to reach correcting circuit PFC purpose.
When VT saturation conductions, it is grounded equivalent to by L right-hand members, at this moment there will be larger current iPFC to flow through L, but due to L's
Inductance characteristic, iPFC can only gradually increase, subsequent VT stoppings, and the energy in inductance L maintains iPFC electric currents to continue to flow, and pass through
D1 charges to C1, and supply load is gradually reduced iPFC, controlled by PFC control circuit, PFC switching tubes constantly open repeatedly,
Close, in load both ends generation output voltage.
If PFC switching tube VT ON times are longer, electric current is larger in L, and the energy put aside in L is more, then when VT ends
When L in the electric current that maintains with regard to larger.Conversely, if VT ON times are shorter, the energy put aside in L is with regard to less, the L when VT ends
The electric current of maintenance is also smaller.It can be seen that the length of control VT service times, you can the size of electric current in control circuit, as long as so pressing
Opening and ending for PFC switching tubes is controlled according to the rule of input voltage, so that it may so that input current is good with input voltage
The same same phase of frequency, improve the input power factor of circuit.
When VT is opened, the polarity of voltage at L both ends is left positive right negative.Now D1 anodes is low, in cut-off state, C2 two
The voltage at end will not be through VT bleed offs.And when VT ends, L both end voltage polarity inversions, for the left negative right side just, the now sense at L both ends
The output voltage of raw voltage and rectifier bridge Q is in series, and C1 is charged by D1, as a result the voltage at C1 both ends exports higher than rectifier
Voltage, therefore this pfc circuit also has boost function.
