摘要： A power converter/inverter system for a load comprises a converter circuit for converting an alternating current power input into a direct current power intermediate signal in response to a first PWM voltage. An inverter inverts the DC power intermediate signal into an AC power output in response to a second PWM voltage. A smoothing filter is arranged in series between a converter and the inverter for filtering the DC power intermediate signal. An instantaneous real power calculating circuit calculates an instantaneous real power (IRP) relative to the inverter and is determined by a torque current command value and a load angular speed signal. A converter controller controls the first PWM voltage of the converter in accordance of a combination a predetermined converter amplitude setpoint, a DC voltage present at the DC power intermediate signal, and the instantaneous real power product. An inverter controller controls the second PWM voltage of the inverter in accordance with the inverter amplitude setpoint and amplitude of the AC power output.
