Abstract

PURPOSE: To perform smooth switching from a start operation to a normal operation and vice versa regardless of power requirement conditions by providing a start circuit with a charge resistor, a discharge resistor, a discharge diode, a trigger capacitor, a bidirectional trigger diode.
CONSTITUTION: A terminal voltage Vc on a trigger capacitor 43 is varied from a trigger start voltage V1 to a trigger termination voltage V2 and vice versa with a period τ1 to drive a switching transistor 3 and increase a bias voltage Va. In the normal operation, the switching transistor 3 is fluctuated between the V3 to the V4 and vice versa with a period τ2 in synchronism with the on-off period, if the voltage V3 will not reach the trigger start voltage V1, this start circuit serves to drive the switching transistor 3 in the starting time until the bias source will reach a sufficient voltage. Whereby if the transistor 3 is triggered to a normal condition, the bias source is cut off from the transistor 3.
