ABSTRACT:
In an AC motor drive, a voltage-source inverter is provided in the DC-link thereof with a GTO switching arrangement which upon braking allows matching the voltage, current domains for the forward power and regeneration modes, the GTO devices being interrupted with a duty cycle selected in response to the voltage difference between the inverter DC input voltage and a constant reference voltage.
