Title:
力率補正回路
Document Type and Number:
Japanese Patent JP4580849
Kind Code:
B2
Abstract:
A primary winding (18) of the transformer (16) comprises a terminal that is coupled to an output of the bridge diode (12) and an another terminal of the primary winding is coupled to an anode of the diode (22). A switching controller (100) controls a duration of a turn-on interval of the switch in response to the received voltage induced in secondary winding which is coupled to the primary winding, when the switch is turned on.
