Abstract

Modular power conversion offers many technical and economic advantages as long as power sharing between modules is maintained. Power sharing through decentralized control (requiring no communication between modules and no central controller) offers the greatest flexibility. A droop-less decentralized control strategy has recently been demonstrated to achieve modular power sharing by incorporating nonlinearity in the integrator term in the control loop. This paper experimentally investigates the application of this control to input-parallel-output-parallel (IPOP) converters with buck output stages. It is found that converters with voltage-source-like characteristics at dc (such as voltage-mode CCM buck converters) require special consideration compared to other converters. The paper also explores the effect of this control on transient response. These features are demonstrated experimentally for voltage-mode and current-mode buck converters, including the effects of module-to-module variability.

IPOP Buck转换器的分散式功率共享

模块化电源转换提供了许多技术和经济优势，只要模块之间的电力共享保持。通过分散控制(不需要模块之间的通信，也不需要中央控制器)实现电力共享，提供了最大的灵活性。一种无下垂分散控制策略最近被证明是通过在控制回路的积分器项中加入非线性来实现模块化的功率共享。本文实验研究了该控制在降压输出级的IPOP(输入-并联-输出-并联)变换器中的应用。研究发现，与其他变换器相比，具有类似直流电压源特性的变换器(如电压型CCM降压变换器)需要特别考虑。本文还探讨了这种控制对暂态响应的影响。这些特性在电压模式和电流模式降压转换器的实验中得到了证明，包括模块间变异性的影响。

期刊介绍： COMPEL exists for the discussion and dissemination of computational and analytical methods in electrical and electronic engineering. The main emphasis of papers should be on methods and new techniques, or the application of existing techniques in a novel way. Whilst papers with immediate application to particular engineering problems are welcome, so too are papers that form a basis for further development in the area of study. A double-blind review process ensures the content''s validity and relevance.
