摘要

随着新一代宽禁带半导体器件在双主动全桥（DAB）变换器中的应用，变换器交流侧出现较高的电压上升率（dv/dt）。高dv/dt含有丰富的高频谐波成分，引起变压器分布电容与系统感性元件之间产生严重的高频振荡问题。该文基于高频变压器π型三电容分布参数模型，推导了变压器端口电压高频振荡的时域解析方程，定量分析了dv/dt和变压器分布电容对高频振荡幅值的影响，并通过调节系统dv/dt实现了对高频振荡幅值的抑制。搭建了DAB变换器实验样机系统和对应的LTspice电路仿真模型，验证了高频振荡问题理论分析的合理性和正确性。

Abstract

The new generation of power devices with wide bandgap semiconductors in dual active bridge (DAB) converters can produce higher voltage rise rates (dv/dt) on the alternating current (AC) side of the DAB converter. However, the many harmonic components in dv/dt lead to undesired high frequency oscillations between the distributed capacitance of the transformer and the inductive components of the DAB converter. This paper presents a time domain analytical equation for the high frequency oscillations of the transformer voltage in a π-type distributed parameter transformer model with three capacitances. The various factors influencing the oscillations are analyzed mathematically with the conclusions that dv/dt and the transformer capacitance are the main factors influencing the high frequency oscillations and that the oscillation amplitudes are reduced by reducing dv/dt in the converter. This paper also uses an experimental DAB prototype together with its corresponding circuit model based on LTspice to verify the theoretical analysis of the high frequency oscillations by simulations and experiments.
