摘要

针对应用于高速动车组电力电子变压器中的单相级联H桥整流器易受网侧电压传感器故障影响的情况展开研究，提出了基于虚拟磁链估算的单相级联H桥整流器无网侧电压传感器控制方法，并进行了仿真验证。首先建立了单相级联H桥整流器,d,-,q,坐标系下的数学模型，根据三相系统中无网侧电压传感器控制算法原理，提出了采用虚拟磁链估算的,d,-,q,电流解耦控制方法，解决了单相级联H桥整流器无网侧电压传感器控制问题；然后搭建相应仿真模型，模拟了整流器多种复杂工况，验证无网侧电压传感器控制算法的稳定性，同时与有网侧电压传感器控制算法进行了对比。仿真结果表明，无网侧电压传感器控制基本能够达到有网侧电压传感器时的控制性能。

Abstract

This paper focused on the single-phase cascade H-bridge rectifiers used in high-speed EMU power electronic transformers, which was susceptible to grid-side voltage sensor failure. A control method for single-phase cascaded H-bridge rectifiers based on virtual flux estimation without the grid-side voltage sensor was proposed and verified by simulation experiments. In this paper, a mathematical model in the ,d,-,q, coordinate system of a single-phase cascaded H-bridge rectifier was established first, then a ,d,-,q, current decoupling control method using virtual flux estimation was proposed based on the principle of the none grid-side voltage sensor control algorithm used in the three-phase system, which solved single-phase cascaded H-bridge rectifier’s no grid-side voltage sensor control problems. Later, a corresponding simulation was set up to simulate a variety of complex working conditions of the rectifier, verify the stability of the control algorithm, and compare with the method based on grid-side voltage sensor control algorithm. The results showed that the control method proposed in this paper can basically achieve the control performance with the grid-side voltage sensor.
