Half-Bridge Converter Modeling and Simulation Based on the Conservation of Energy Averaging Circuit

本文针对电力电子领域开关变换器分析模型的建立问题,分析了能量守恒平均电路法建立周期性、时变性开关变换器模型的基本思路。并运用该方法建立了半桥逆变全桥整流DCDC变换器的分析模型,得到传递函数。通过MATLAB仿真证明所建立的模型与所得到的传递函数的有效性。

This paper discusses establishment issues of analysis model of the switching converter, and analyzes the basic idea of the Conservation Energy-Average Circuit Act for switching converter model. The model and the transfer function of half-bridge inverter full bridge rectifier DCDC converter is established by using CEACA. The simulation in MATLAB proves the validity of the Conservation Energy-Average Circuit Act.
