Abstract

The demand for high voltage, high power, high precision and high dynamic 3AC-voltage sources is increasing constantly. One application that gets more and more important in recent years and demands such voltage sources is e.g. Power-Hardware-in-the-Loop (PHIL) Emulation. In this paper a new power converter topology called “Parallel Hybrid Converter” or PHC is presented and a corresponding control scheme is derived. This new converter has a terminal behavior similar to a MMC or MMPMC but compared to them the PHC features significantly reduced costs and a significantly improved power density.

基于级联h桥的并联混合变换器——一种完美正弦高电压源的新型拓扑结构
对高压、大功率、高精度、高动态的3ac电压源的需求不断增加。近年来越来越重要的一个应用需要这样的电压源,例如电源-硬件在环仿真。本文提出了一种新的电源变换器拓扑结构,称为“并联混合变换器”(PHC),并推导了相应的控制方案。这种新型转换器具有类似于MMC或MMPMC的终端行为,但与它们相比,PHC具有显着降低成本和显着提高功率密度的特点。
