带有二次侧谐振电感的LLC谐振变换器并联绕组自动均流技术

The current sharing issue of paralleled secondary windings of the transformer is a major concern of LLC resonant converters. Matrix transformers solve this issue by connecting primary windings in series and secondary windings in parallel, but the volume and loss of magnetic cores increase dramatically. This letter proposes a modified LLC resonant converter, which can achieve automatic current shar...
