一种带耦合电感的有源钳位高增益Boost变换器
An Active-clamp High Step-up Boost Converter With Coupled-inductor
摘要
Abstract
This paper proposed an active-clamp high step-up boost converter with coupled-inductor. The voltage gain of the boost converter was improved by introducing a coupled inductor. The active clamp circuit was employed to recycle the leakage energy, suppress the switch turn-off voltage spikes, and implement zero-voltage-switching turn-on operation. The reverse-recovery problem of the diodes was solved by the reasonable design of the leakage inductance. The main limitation of the proposed converter is the high peak voltage of the diode due to the resonance between the leakage inductor and parasitic capacitor of it, and a resistor-capacitor-diode (RCD) snubber circuit should be included. A 250 W prototype with 48 V-input and 380 V-output was built and the experimental results verify the correction of the theoretical analysis, the highest measured efficiency is about 94.5%.关键词
