本文给出了降压、升压、单绕组和双绕组升—降压型四种基本开关稳压器的统一的稳态分析。这个分析作为一种系统设计方法的基础,这种设计方法已用问答式计算机辅助设计程序付诸实现,这种程序能够使不熟练的设计师选择和设计最适合自己特殊问题的开关稳压器。这种程序还算了储能电感,并且,在可能解的一览表上指出了从质量、体积和效率方面看来都是最佳的电感值。 This paper presents a unified steady-state analysis of the buck, boost, single-winding and dual-winding boost-buck four basic switching regulators. This analysis serves as a basis for a system design methodology that has been implemented using a question-and-answer computer-aided design program that enables unskilled designers to select and design switching regulators that best suit their particular problems . This program also calculates the energy storage inductance and, on the list of possible solutions, indicates the best inductance value in terms of mass, volume and efficiency.
