Title:
POWER CONVERSION CIRCUIT
Document Type and Number:
WIPO Patent Application WO/2019/069489
Kind Code:
A1
Abstract:
The present invention obtains a power conversion circuit for obtaining a power conversion device in which charging/discharging of a parasitic capacitance by high-frequency switching is suppressed to reduce the loss of a semiconductor switching element. The power conversion circuit includes: a circuit board constituted by two or more layers by which a circuit pattern is formed; and a plurality of semiconductor switching elements connected to the circuit pattern of the circuit board and performing switching for power conversion. In the circuit board, a plurality of control ground patterns of different nodes through which the plurality of semiconductor switching elements are driven are disposed so as not to be overlapped with each other in a plan view.
