一种具有新型原边控制的半桥谐振变换器的设计与实现

The opto-coupler is usually used for isolated resonant converter to feedback the secondary-side output information. However, the characteristics of the opto-coupler are easily affected by the operating conditions, which will cause higher standby power loss. In this article, a novel primary-side controlled isolated half-bridge resonant converter with output voltage and current estimation for LLC an...
