電動車に接続して使用される電力変換装置
Document Type and Number:
Japanese Patent JP6075878
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a power conversion device of a V2H (Vehicle to HOME) system, capable of surely preventing a pseudo commercial AC power of a wrong frequency from being supplied to a load during a power failure, while improving usability by reducing a user burden.SOLUTION: A control section 3 of a power conversion device 1 includes: a frequency determination part 3C for determining a frequency of commercial AC power; a non-volatile storage part 3E for storing determined frequency data of the commercial AC power; a discharge control part 3B in which, in a case where supply of the commercial AC power is interrupted, a bidirectional power conversion part 2 is made output a pseudo commercial AC power of a frequency same as the frequency data stored in the storage part 3E; and a frequency verification part 3D for verifying whether the frequency data stored in the storage part 3E are destroyed, before the discharge control part 3B refers to the frequency data. While an auxiliary power storage section 4 supplies power to the control section 3, the frequency verification part 3D stores finally determined frequency data into the storage part 3E.
