Title: Uninterruptive power supply device
Inventor: OKUI YOSHIAKI
IPC: H02J3/18
Filed: 2000-09-22
Abstract: PROBLEM TO BE SOLVED: To provide an uninterruptive power supply device in which distortion of an output voltage can be reduced than is possible conventionally. SOLUTION: A DC voltage control circuit 11A of a current control system 11 seeks an input current command value based on a multiplication value with a difference voltage between a DC voltage command and DC side voltage of a power conversion device and an output of a reference voltage creation circuit 13. A current control circuit 11B outputs the value obtained by deducting a load current value passing through the load and a current value which flows in the power conversion device from the A.C. side from an input current command value, as a current control command. When an abnormal voltage detecting circuit is detecting an instantaneous anomaly, and alternating current Iin which flows through an A.C. switch is used as input current command value.
