Abstract

PURPOSE: To accomplish on/off operation of a main switching element by means of a reverse-current semiconductor provided in the circuit between the main switching element and the load.
CONSTITUTION: A diode D3 having polarity as illustrated is inserted into the circuit betwenn the cathode side of a second S2 and a common connection point CO2. One end of a dummy load RD having a high resistance of 500Ω for instance is connected to the point CO2 between the diode D3 and the thyristor S2, while the other end thereof is connected to an auxiliary bus N. Even when the load voltage rises as the load current is down to the extreme low lovel, the diode D3 works to ensure accurate on/off operation of the thyristor S2.
