一种谐振复位单端正激电路的设计

基于谐振磁复位技术,设计了一种单端正激变换器,通过变压器激磁电感和谐振电容,将变压器磁芯能量转换到输入源,并防止变压器磁芯饱和。在转换过程中,激磁能量通过准正弦波的形式,先由变压器激磁电感传递到谐振电容,再由谐振电容传递到输入源。对这种电路的设计方法进行了探讨,用具体电路说明了优化设计过程。

Design of Resonant Reset Single-Ended Forward Converter

A single-ended forward converter was designed based on resonant reset technique,which resets transformer core flux to prevent saturation and returns magnetizing energy to the energy source by resonant commutation of the magnetizing inductance and resonating capacitor.This magnetizing energy transfers from magnetizing inductance to resonating capacitor with a resonant quasi-sine wave,then flows back to the input voltage source with a quasi-sine wave.Design methodology and optimization of the circuit were discussed and illustrated with a specific circuit.
