    The aim of the invention is to provided a PWM cycloconverter that can compensate for the error between a voltage command generated in response to a commutation and a real voltage. The PWM cycloconverter comprises an input voltage phase detector (6) for detecting the voltage phase of a three-phase AC power supply (1); a current direction detector (7) for detecting the direction of a current flowing through a bidirectional semiconductor switch (3); and a commutation compensator (11) for receiving the outputs from the input voltage phase detector and current detector to compensate for the voltage command.
