The high-power high-frequency switch power supply that electric automobile battery charger adopts, by the uncontrollable rectification circuit of three-phase bridge, three-phase alternating current input is carried out to filter rectification, the pre-voltage stabilizing 800V of power factor correction is by high frequency DC/DC half-bridge power converter, and filtering output direct current 700V is power accumulator charging.Calculate by analysis, the two E65 magnetic cores of transformer adopting, primary coil 12 circles, according to the highest 700V of output voltage, the minimum 780V of input voltage, maximum duty cycle 0.95, can try to achieve secondary winding number of turns N2, N2=(12/780) * (700/0.95)=11.33, consider that it is 12 circles that the factors such as leakage inductance, secondary commutation pressure drop are got N2.
Because electric automobile battery charger is nonlinear-load, can produce harmonic wave, to electrical network, be a kind of pollution.Must adopt an effective measure, as technology such as power factor correction or reactive power compensations, restriction electric automobile battery charger enters total harmonic content of electrical network.For improving power factor, reduce input mains by harmonics, adopt APFC, it adopts three-phase three switch three lever BOOST circuit, is operated in continuous mode, and switch adopts two bidirectional switchs that MOSFET is combined into.Due to the symmetry of circuit, electric capacity midpoint potential is approximate identical with the current potential of electrical network mid point, thereby can control respectively the corresponding electric current of going up mutually by bidirectional switch.The current amplitude that when switch closes, correspondence goes up mutually increases, and (electric current is timing to diode current flow when switch disconnects on corresponding brachium pontis, upper arm diode current flow; When electric current is negative, underarm diode current flow).Electric current under the effect of output voltage on Boost inductance reduces, thereby realizes the control to electric current.Its control circuit adopts three control chip UC3854A, phase voltage provides synchronizing signal and precorrection signal by three-phase isolation transformer to UC3854A, current feedback adopts Hall current instrument transformer, control respectively three switches, form many closed-loop systems of the interior ring of three current feedback and a Voltage Feedback outer shroud.The advantage of this circuit is simple in structure, and every phase only needs a power switch.Have three level nature harmonic currents little, switch tube voltage current stress is little.Do not need center line, without triple-frequency harmonics, full load power factor is very high.Switch stress is little, and shutoff pressure drop is low, and switching loss is low, and common mode EMI is low.
DC/DC power inverter adopts half-bridge circuit topology, and power device is few, controls simply, and reliability is high.Adopt MOSFET and IGBT parallel technology, take full advantage of switch mosfet speed soon and the low advantage of IGBT conduction voltage drop.On circuit, take measures, make the turn-off time of MOSFET postpone the regular hour than IGBT, greatly reduced the current tail of IGBT, reduced switch on-state loss, improved efficiency and reliability, make the power output of half-bridge circuit can realize 7kW.The rectifier system that its outlet side adopts has halfwave rectifier, centre cap full-wave rectification and full-bridge rectification.Because output voltage is higher, full-bridge rectification is high to transformer utilization factor, than being more suitable for this high-power charger.
