Abstract
PURPOSE: To make a starting operable at no load, by providing a diode, for reverse current cut-out, between a fly-wheel diode, connected to the output side, diode and the chopper circuit, and providing a dummy-load resistor between said and the chopper circuit.
CONSTITUTION: At starting operation, with a main thyristor in a thyristor chopper circuit 2 turned ON, because of a resistance value of the dummy-load resistor 10 being enough for flowing a holding current of the main thyristor, the thyristor becomes perfectly ON. If applied a voltage to a condenser 6 being charged, a discharge begins to operate, but the current, flowing in the dummy-load resistor 10, is not decreased by the blocking operation of a diode 11, thus with the holding current ensured in the main thyristor. In case of an operation with more than two circuits of the chopper circuit connected in parallel, the current from the condenser 6 is blocked off by coupling diodes 13-1, 13-2, with a current flowing in the dummy- load resistor 10 through diodes 14-1, 14-2, and the holding current of the main thyristor will be ensured.
