Abstract

PURPOSE:To enable to perform the control suitable for a continuous operation of the subject power supply by a method wherein a zero voltage command is generated when the external AC source voltage is abnormal and a command voltage is increased slowly when the abnormal condition is removed. CONSTITUTION:The base of the main circuit transistor constituting an inverter is controlled by the output of the base controlling circuit 20 which consists of an input section 20a and an output section 20b. When the exterior AC power source voltage becomes abnormal, an abnormal voltage signal 300 is inputted, an abnormal time voltage command generator 30 outputs a zero voltage command 302, an analog minor priority circuit 32 outputs a zero voltage command 400 and the output section 20b outputs a zero voltage command 100. Then, when the abnormal voltage signal 300 is removed, the voltage at both ends of the capacitor 38 is increased gradually and the signal 302 is turned into a slowly increasing return voltage. The minor priority circuit 32 outputs the smaller signal either from a return voltage signal 302 and a speed command signal 202 as a signal 400.
