Abstract

PURPOSE:To readily and continuously control the output of the switching power source by deciding the specific phase section of the power source voltage as the operating period of the switching element and providing a control circuit for controlling the duty in this period. CONSTITUTION:The AC current from an AC power source 1 is rectified into a DC current, which is controlled by the switching element 1 to a transformer 3 to drive a load 9 on the basis of the secondary output of the transformer 3. The specific phase sections t1-t2 of the voltage waveform of the AC power source is decided as the operating period of the switching element 4. The current phase is advanced while controlling the duty levels a, b, c in this period to produce a control signal by a control circuit 10. since the width of the period varies in a manner of T1> T2>T3>T4>T5, the energy applied to the load 9 can be freely altered.
