Title:
POWER CONVERSION SYSTEM CONTROL DEVICE AND POWER CONVERSION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2023/218599
Kind Code:
A1
Abstract:
This power conversion system control device comprises: a power converter connected to a power source or to a capacitor via wiring; a coil disposed in a position which is around the wiring and at which, when a short circuit failure has occurred because of voltage in the capacitor or in the power source being short-circuited, magnetic fluxes generated by the short circuit failure are interlinked; and a voltage detection circuit for detecting the voltage value of voltage between both ends of the coil. The power conversion system control device further comprises: a voltage acquisition unit for acquiring the voltage value of voltage between both ends of the coil detected by the voltage detection circuit; and a failure detection unit for detecting a short circuit failure of the power converter on the basis of the voltage value acquired by the voltage acquisition unit.
