摘要

本文提出了一种控制电力电子变压器输入级的混合控制方法。本工作中的电力电子变压器采用AC/DC形式，包括输入整流器和DC/DC降压级两级，用于电力列车等不同应用。该方法基于模型预测控制(MPC)方法，以实现整流级电容器电压平衡和输入功率因数控制为目的。与现有的MPC方法相比，该方法的主要优点是算法简单，计算量比传统的MPC方法显著减少，并且可以同时控制输入电流、输出电压和功率因数，均具有令人满意的性能。仿真结果验证了所设计方法的良好性能。

A Hybrid Control Method Based on Model Predictive Control for Controlling the Rectifier Stage of Power Electronic Transformers

In this paper, a hybrid control method for controlling the input stage of a power electronic transformer is proposed. The power electronic transformer in this work is in form of AC/DC which includes two stages of an input rectifier and a DC/DC step-down stage and is employed in different applications such as electrical trains. The method is proposed based on Model Predictive Control (MPC) approach with the aim of voltage balancing for the capacitors in rectifier stage as well as controlling the input power factor. The main advantages of the proposed method over other existing methods are simple algorithm, notable reduction in the computational burden compared to the conventional MPC method, and simultaneous control of input current, output voltage and power factor, all with satisfactory performance. The proper performance of the designed method is verified by simulation results.
