Abstract
PURPOSE: Power loss of transistor for intermittent duty is decreased and efficiency is improved by supplying voltage from power source circuit at starting and supplying voltage due to chopper output after starting to controll circuit chopper-operating intermittent type transistor.
CONSTITUTION: Primary winding 3 of transformer and transistor 5 for intermittent duty are series-connected with both ends of DC power source circuit 1. The transistor 5 is controlled by controlling circuit 14, whereby secondary winding 6 is output and voltage is generated in tertiary winding 9, while switch circuit 22 controlled by charge voltage of condenser 12 is connected with control circuit 14 by transistor 16 connected with base, whereby power supply to control circiut is limited only at starting and power supply can be reduced, because control circuit 14 is actuated by transistor 16 at starting and is actuated by voltage generated in teritary winding 9 in transformer after starting.
