Power converter

A synchronization detection PLL section (13) generates an ON synchronized signal formed as a result of synchronization control based on a diode ON synthesized signal. The synchronization detection PLL section (13) also generates an OFF synchronized signal formed as a result of synchronization control based on a diode OFF synthesized signal. A stator gate instruction generator PWM section (15, 15') generates a gate instruction signal for controlling the switching of a switching element (31, 33, 35, 37, 39, 311) on the basis of the ON synchronized signal and the OFF synchronized signal.
