Chopping converter i.e. indirect transmission chopping converter, has switching assistance circuit comprising inductor, capacitor and diodes, and energy recovery transformer whose primary is managed by inductor

摘要

The converter has a passive and dissipative switching assistance circuit i.e. snubber circuit, comprising an inductor, a capacitor (C1) and diodes (D1, D2), and an energy recovery transformer (TR2) whose primary is managed by the inductor of the switching assistance circuit. The energy recovery transformer is indirect transmission type, and comprises an output connected to primary or secondary of the converter.
