Abstract

PURPOSE:To enhance the switching reliability of a switching circuit composed of a current limiting reactor, a semiconductor switching element, a flywheel diode, and a snubber circuit by connecting a diode antiparallel to the switching element having no reverse blocking. CONSTITUTION:Only one phase of an inverter used for motor control or the like is shown. A switching circuit composed of current limiting reactors 38, 39, semiconductor switching elements having no reverse blocking (e.g., short emitter type gate turn off thyristors) 6, 9, flywheel diodes 12, 15, elements 18, 30, 14 and 21, 33, 37 as snubber circuit is connected between the DC input terminals 1 and 2, and AC output is produced from the terminal 3. Diodes 40, 41 are so connected additionally as to be antiparallel to the elements 6, 9 to reduce the reverse voltage applied to the elements 6, 9.
