Embodiment
Below in conjunction with accompanying drawing the utility model is done further detailed explanation.
Electric machine controller hardware circuit as shown in Figure 1 comprises a three-phase inverter, and the DC side of this three-phase inverter connects dc bus; DC side is provided with the dc bus filter capacitor C1 and the brake module of parallel connection, and brake module comprises the brake module power device V7 and the brake module power resistor R1 of series connection.
As optimization, be parallel with a brake module sustained diode 1 on the power resistor R1, the negative pole of this brake module sustained diode 1 connects the dc bus anode.Be parallel with overpressure absorbing circuit on the brake module power device V7, this overpressure absorbing circuit is the resistance R 2 and capacitor C 2 of series connection.
For DC bus-bar voltage is carried out intuitive judgment, also be provided with high-voltage indicating circuit on the dc bus, this high-voltage indicating circuit is made up of the current-limiting resistance R3 and the light-emitting diode D2 of series connection.
Electric machine controller also comprises master control, driving and the power circuit based on above circuit.
The function of V7: major loop PWM performer; The function of D1: when V7 turn-offs, the loop afterflow; The function of R2 and C2: absorb the overvoltage that produces when V7 turn-offs.
Operation principle:
1, after electric machine controller dc bus and vehicle-mounted electrical source of power high direct voltage were connected, high-voltage indicating circuit was started working, and electric current flows through light-emitting diode D2 after resistance unit R3 current limliting.The brightness of light-emitting diode D2 is along with the electric machine controller DC bus-bar voltage goes up and down to change.
When 2, motor was in motoring condition work, brake module was not participated in electric machine controller work, and Electric Machine Control is carried out according to routine control.
3, motor is in on-position work, and when needing the energy feedback, control chip is controlled brake module according to the retarder function, rated output resistance the electric flux that will consume, the switching frequency and the pulsewidth of brake module power device are set.Control circuit carries out PWM control through the switch of drive circuit power controlling device V7 to it, and the energy consumption that produces during with motor braking is on power resistor R1, to reach the retarder function.
4, after electric machine controller dc bus and vehicle-mounted electrical source of power high direct voltage were broken off, the brake module power device was according to decide frequency and deciding pulsewidth work, with electric machine controller dc bus filter capacitor energy stored with form of heat consumption.
Retarder function control strategy:
1, judge whether this function carries out automatic mode, if automatic mode, execution in step 2; If manual mode, execution in step 4.
2, confirm the braking moment that current motor need produce, judge whether the capacity of vehicle-mounted electrical source of power reaches 100%, if reach, execution in step 4; If do not reach, execution in step 3.
3, confirm the absorbent ceiling capacity of current vehicle-mounted electrical source of power.
4,, carry out power and revise certainly according to the work gear that the buffer gear is selected or automatic mode is provided with down automatically.Calculate brake module power circuit operating frequency and pulsewidth through revising the result certainly, power controlling circuit output PWM ripple.
5, judged whether that defencive function interrupts, whether stops the retarder function and whether motor speed is that any one of 0,3 alternative condition is true, execution in step 6; 3 alternative conditions all are false, execution in step 1.
6, stop power circuit output PWM ripple, the associative operation button resets.If, get into the traditional braking pattern because of defencive function interrupts stopping power circuit output PWM ripple.Finish.
Concrete control strategy flow chart is seen accompanying drawing 2.
