Abstract
PURPOSE:To enhance the conversion efficiency of the inverter by cutting off a switching element which controls the exciting current of a transformer by the timing signal from a timing circuit before the transformer core is saturated. CONSTITUTION:When the induced voltage of a feedback coil F1 becomes positive at the time of t0, a transistor Q1 is conducted, and a transistor Q3 is in a cut off state. During this period, a capacitor C2 is charged through a resistor 5, and the timing signal which conducts the transistor Q3 is generated at time t1 after the elapse of a timer period. As a result the base current of the transistor Q1 is bypassed, and the transistor Q1 is cut off at the time t2. The timer period increases when the exciting current for the primary coil P1 begins to flow, and the time is selected at the point before the core is magnetically saturated. Therefore, the core is not saturated, the load of the switching element is light, and the conversion efficiency of the inverter can be enhanced.
