Development and Analysis of Capacitor Charge Balance Control Technique

随着高性能数据处理设备的迅速发展,电力电子供电设备动态响应的要求也越来越高。先进控制技术是提高变换器动态响应的一种有效的方法。近年来提出的基于电容电荷平衡准则的控制策略可以使变换器既具有快速负载动态响应又有较高的效率。这种控制策略大致可以分为两类:仅通过控制电路来实现快速负载响应;通过控制电路和改变主电路的结构来实现快速负载响应。文中回顾了近年来电容电荷平衡控制技术的研究进展,并分析讨论了它们的特点。

With the development of high-perfomlance digital devices, the demand on the power electronics industry to supply such devices becomes increasingly complex. A relatively inexpensive method to improve the dynamic response of a converter is to improve its controller. The converter using the control method based on capacitor charge balance technique is of the advantages of rapid response and high efficiency. A number of the premier topologies were reviewed. The performance characteristics were evaluated.
