基于非隔离耦合电感的零直流励磁电流高降压变换器

A nonisolated coupled-inductor-based high step-down converter with zero dc magnetizing inductance current and nonpulsating output current is presented. Since the dc magnetizing inductance current is zero, the magnetizing current can be positive and negative. Therefore, the entire core B-H loop can be used, ranging from the first quadrant to the third quadrant. That is, the utilization of the coupl...
