Title:
CREST CURRENT REDUCTION CIRCUIT DEVICE IN SWITCHING REGULATOR
Document Type and Number:
Japanese Patent JPS62110476
Kind Code:
A
Abstract:
A circuit for reducing peak current in dependence on line voltage in a blocking oscillator-switched power supply, includes a transformer having a primary winding and a control winding, an electronic switch connected in series with the primary winding, and a control circuit supplied by the control winding for controlling the electronic switch, the control circuit including a pulse processing stage addressed by rectified a-c line voltage fed into the primary winding, a start-up stage, and a variable voltage coupling stage coupling the pulse-processing stage to the start-up stage.
