Abstract

In this paper, the modelling and control design for a double-inductor boost converter with power factor correction capability (PFC-DIBC) is proposed. The PFC-DIBC is coupled to the electrical grid by a rectification stage, formed by a full-bridge diode rectifier, then a high gain DC-DC DIBC stage feeds the DC load with a fixed voltage level. The main advantage of this configuration is the presence of the DC-DC DIBC which is capable to provide a high conversion ratio for the output voltage. The proposed controller is based on the average model of the system and consists of two main control loops: a current tracking loop and a voltage regulation loop. The first is aimed to force the line current to track a sinusoidal current reference proportional to the grid voltage and the second objective is aimed to regulate the output voltage to a desired reference. Finally, to assess the performance of the proposed controller numerical simulations of the system using PSCAD software are presented.

基于双电感升压变换器的功率因数补偿器控制策略

提出了一种具有功率因数校正能力的双电感升压变换器(PFC-DIBC)的建模和控制设计。PFC-DIBC通过整流级耦合到电网，整流级由全桥二极管整流器形成，然后高增益DC-DC DIBC级以固定电压电平为直流负载供电。这种配置的主要优点是DC-DC DIBC的存在，它能够为输出电压提供高转换率。该控制器基于系统的平均模型，由两个主要控制回路组成:电流跟踪回路和电压调节回路。第一个目标是迫使线路电流跟踪与电网电压成比例的正弦电流基准，第二个目标是将输出电压调节到所需的基准。最后，为了评估所提出的控制器的性能，使用PSCAD软件对系统进行了数值模拟。
