Abstract

PURPOSE:To make the entire device small in size, by partly using a component of two sets of unidirectional DC solid-state circuit brackers commonly to bidirectional applications. CONSTITUTION:A communication circuit is made to a bridge connection, the circuit interruption for bidirectional currents is made possible with one set of a commutation capacitor 16 and a communication reactor 17, and the energy stored in the inductance of a power supply 10 and a load 22 at failure is absorbed in a metal oxide system nonlinear resistor 13. Thus, the rapid absorption of the current is made possible, and an insulation resistance between terminals is made substantially infinite after a failure current disapperas through the selection of a limit voltage of the nonlinear resistor to 1.5 to several times the DC power supply voltage to keep the circuit opened. Thus, the size can be made small.
