用于宽电压范围应用的带钳位电感混合三电平全桥隔离Buck-Boost变换器

An isolated buck-boost (IBB) converter with a hybrid three-level full-bridge primary-side circuit is proposed to achieve wider voltage range regulation. The primary-side circuit is composed of a three-level leg and a two-level leg. The output voltage of the primary-side circuit is five level (i.e., ±Vin, ±Vin/ 2, and zero), and the secondary-side circuit is a semiactive full-bridge rectifier with ...
