Abstract
Official abstract text for this publication.
A switching power converting apparatus includes a voltage conversion module, a detecting unit, and a switching signal generating unit. The voltage conversion module converts an input voltage into an output voltage associated with a secondary side current, which flows through a secondary winding of a transformer and is generated based on a switching signal. The detecting unit generates a detecting signal based on the output voltage and a predetermined reference voltage. The switching signal generating unit generates the switching signal based on the detecting signal and an adjusting signal so that the secondary side current is gradually increased during a start period of the switching power converting apparatus.
First claim
Opening claim text (preview).
What is claimed is: 1. A switching power converting apparatus comprising: a voltage conversion module including a transformer, wherein said transformer includes a primary winding adapted to receive an input voltage, a first secondary winding and a second secondary winding, wherein said voltage conversion module is operable, based on a switching signal having a switching frequency, to generate a secondary side current flowing through said first secondary winding of said transfor…
