Abstract
A controller of a power converter including an inverter that includes plural semiconductor switching elements. The controller suppresses an error between a voltage command and an inverter output voltage and responds to a voltage command at a high speed. The controller includes a voltage command generator that generates a voltage command signal and a switching pattern calculator that calculates and outputs, based on the voltage command signal, a switching pattern of a synchronous PWM system in which an average value of an inverter output voltage matches the voltage command signal.
