Abstract
Provided is a power conversion circuit for achieving a power conversion device capable of suppressing charging/discharging of a parasitic capacitor caused by high-frequency switching, and of reducing a loss of a semiconductor switching element. The power conversion circuit includes: a circuit board including a plurality of layers including two or more layers, on which circuit patterns are formed; and a plurality of semiconductor switching elements connected to the circuit patterns of the circuit board, and configured to perform switching for power conversion. In the circuit board, a plurality of control ground patterns for different nodes, which are configured to drive the plurality of semiconductor switching elements, are arranged so as not to overlap one another in plan view.
