Document Type and Number:
WIPO Patent Application WO/2017/158880
Kind Code:
A1
Abstract:
A power conversion device (1) having: a three-phase detection part (14) for detecting a phase failure and phase reversal of each phase on the basis of a phase difference between two phases of a three-phase three-wire system 3 comprising R-phase, S-phase, and T-phase; and a module control power supply part (13) for generating drive control power for driving a power conversion module from the three-phase three-wire system 3. The device is equipped with an N-phase phase failure detection part (15) for detecting a phase failure of N-phase by using the drive control power.
