Title:
POWER CONVERSION CIRCUIT AND CONTROL SYSTEM
Document Type and Number:
WIPO Patent Application WO/2024/058277
Kind Code:
A1
Abstract:
The present invention provides a power conversion circuit that can be operated while suppressing degradation in the properties of a gallium oxide semiconductor. This power conversion circuit at least includes a switching element, and a control unit that detects short-circuiting of the switching element and performs an off-operation for the switching element on the basis of the detection result, wherein the switching element includes a gallium oxide semiconductor, and the control unit controls the off-operation of the switching element such that the time from the occurrence of the short-circuit to the off-operation is less than 1.4 μsec.
