Abstract
PURPOSE: To perform effecient pulse driving with a small magnetizing current by varying the time length of the OFF period with the ratio between the ON period and OFF period being kept constant.
CONSTITUTION: The primary winding N1 and the secondary winding N2 of a current transformer T2 are connected to a control switch Q2' and GTO Q1', respectively. A series circuit of a diode D and a short-circuit switch Q3 is connected to a tertiary winding N3 so that the tertiary winding N3 is shorted for a specified period only against a counter emf generated after turning OFF the switch Q2'. In this constitution, the OFF period of the switching element can be varied without fluactution of the exciting current, thereby efficient pulse driving can be performed.
