Title: Pwm cycloconverter
Inventor: YAMAMOTO EIJI
IPC: H02M7/48
Filed: 2000-03-09
Abstract: PROBLEM TO BE SOLVED: To change a power supply without interrupting operation even if power failure occurs in the power supply. SOLUTION: When power failure occurs in a three-phase AC power supply 1, a power failure detection signal 120 is outputted by a power failure detection circuit 30, thus enabling a power supply switcher 20 to select the output voltage of an uninterruptible power supply 10 for outputting.
