摘要：

Switching power converter design and control are often constrained by the performance of available devices. This is particularly true in low-voltage circuits. A method for creating 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. These high-performance modules can be configured to emulate diodes, thyristors, special resonant devices, or nearly any other switch type. The control is autonomous-it depends on the terminal behavior and external gate signals and requires no additional information from the application circuit. Experimental examples of several switch modules in low-voltage power converters are given. The experimental modules use power MOSFET's and give performance similar to that of synchronous rectifiers but with much greater flexibility. For instance, a module configured to emulate an SCR shows voltage drops below 0.25 V at several amperes of forward current.
