This paper proposes that wireless time synchronization by GNSS (Global Navigation Satellite System) can be applied to the control of power conversion circuits, and clarifies its validity through experiments. This paper shows that a highly accurate synchronization can be obtained by employing a synchronization system based on GNSS. Moreover, the control signals of each power device in a half-bridge inverter are connected to a controller with GNSS and driven using 10kHz switching, which enables operation of the power conversion circuit without causing a leg short circuit.
