基于数字化的三电平Boost PFC变换器临界导通模式控制

Conventional critical conduction mode (CRM) control for many boost-derived power factor correction (PFC) circuits forms triangular inductor current. For three-level boost (TLB) converter, the conventional method is unattractive because losses increase but waveform quality remains unchanged, compared to other topologies. In order to obtain higher efficiency and improved waveform qualities, this art...
