ENERGY CONSUMPTION CIRCUIT, OUTPUT DEVICE, AND OUTPUT SYSTEM

摘要

PROBLEM TO BE SOLVED: To achieve downsizing and a long service life of a recovery circuit which performs recovering operation of regenerative energy of a motor 14 supplied through an inverter 13.

SOLUTION: An output system comprises: an energy consumption circuit 15 which includes two recovery circuits 1 and 2 in parallel capable of performing recovering operation of regenerative energy of a motor 14 supplied through an inverter 13; and a direct current (DC) voltage output circuit 40 which outputs DC voltage VB2 to be supplied to the inverter 13 through transmission routes 51 and 52 of regenerative energy. Each of the recovery circuits 1 and 2 are connected to an inverter 14 in parallel. The number of the circuits performing the recovering operation of the recovery circuits 1 and 2 varies depending on the magnitude of the regenerative energy.
