Abstract

Herein, we propose a control method for a single-phase active filter composed of a universal smart power module (USPM). The USPM is a modularization technology concept that comprises various power conversion systems. Depending on the application, the USPM is a full-bridge inverter with a wideband controller and filter, and the power converter is constructed using several USPMs. In this study, the target system was an active filter composed of modules connected in series or parallel to accommodate arbitrary voltage and current capacitances. The proposed method solves the communication delays between the master and slave controllers owing to the distributed control in wireless communications and the interference problem caused by multiple USPM connections. The experimental results of the steady-state response showed that despite the communication delays, the total harmonic distortion (THD) of the input current was improved by up to 63.0%, and the power factor was 0.997. Moreover, load fluctuation experiments confirmed that the system transitioned to a steady -state and operated stably by updating the command value of the slave controller for the first time after the load fluctuation. The harmonic current elimination can be realized as an active filter, and the effectiveness of the proposed method was confirmed.

基于通用智能电源模块的单相有源滤波器控制方法

本文提出了一种由通用智能电源模块(USPM)组成的单相有源滤波器的控制方法。USPM是一个模块化的技术概念，包括各种功率转换系统。根据应用的不同，USPM是一个带宽带控制器和滤波器的全桥逆变器，功率转换器由几个USPM组成。在本研究中，目标系统是一个由模块串联或并联组成的有源滤波器，以适应任意电压和电流电容。该方法解决了无线通信中由于分布式控制而导致的主从控制器之间的通信延迟以及多个USPM连接造成的干扰问题。稳态响应实验结果表明，尽管存在通信延迟，但输入电流的总谐波失真(THD)提高了63.0%，功率因数为0.997。此外，通过负载波动后第一次更新从控制器的命令值，验证了系统过渡到稳态并稳定运行。谐波电流消除可以通过有源滤波器实现，验证了该方法的有效性。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
