Robert, Similar in that an inductor in a buck converter is used to create a (possibly variable) lower voltage than the input by modulating the switch to open only a part (variable) of the time, so the output voltage becomes the percentage of opening multiplied with the input voltage, so also a

I can conclude from what you say that during regen mode none of the IGBTs are energized. Therefore, only during drive operation are the IGBTs switched. Since the car is slowing down during deceleration, the motor RPMs are decreasing. At some point, the voltage generated by the motor will

Ing. Marco Gaxiola via EV wrote: I agree with robert, how the inverter is capable of 'charge the battery' from regen when at very low RPMs? OK, the first key to understanding is that the six IGBTs each have a diode connected across it. The six diodes are wired in a standard 3-phase
