Abstract
A power converter has one set of two semiconductor switches performing switching actions, each of which is formed of an FET and a free wheel diode connected in anti-parallel to the FET, and a smoothing capacitor, and convers power by complementary switching actions of the FETs in the semiconductor switches. The power converter is provided with a current sensor that detects a direction of a current flowing through the semiconductor switches and a gate generation portion that skips ON signals of PWM gate signals of the semiconductor switches when the direction of the current flowing through the semiconductor switches is negative.
