中文摘要

本文提出了一种推导具有宽三阶电压转换比的DC/DC变换器拓扑的方法。基于伏秒平衡方程,定义了两组参数来描述拓扑结构,并推导了电压转换比系数。随后,通过设定参数约束(如避免输入电流脉动等),实现了对高性能变换器拓扑的系统性筛选与优化。

English Abstract

This article introduces a method for deducing the topology of a dc/dc converter with wide third-order voltage conversion ratio. Initially, two sets of parameters are proposed to describe the topology based on the volt-second balance equations, and the coefficients of the voltage conversion ratio in terms of these parameters are derived. Subsequently, parameter constraints, such as avoiding input o...
