一种实现宽增益范围和效率优化的谐振正激变换器改进级联方案

This article presents an improved cascading scheme for the resonant forward converter to widen the gain range while reducing losses and complexity by removing two filtering components. The efficiency is optimized for the second stage through the phase-shift-controlled current injection directly from the first stage. Then, the improvement is achieved by adaptively adjusting the resonant duration ac...
