Abstract

A method for building high-performance switch modules from power transistors and simple control circuits is presented. The method is based on switching function principles: any type of switch can be represented by an ideal switch in combination with basic logic elements. The high-performance modules can be configured to emulate diodes, thyristors, or any other switch type. The control is autonomous-it depends on the terminal behavior, not on the overall circuit behavior. Practical implementation examples are given, based on power MOSFETs. The experimental modules give performance similar to that of synchronous rectifiers, but with much greater flexibility
