Test and design of switching mode regulators using the behavioral averaged PWM switch and a program for automatic regulator prototype generation

One of the most critical and time consuming tasks in power electronics is the design and testing of regulators used in the compensation of switching power converters. Methods of trial and error are frequently applied to small signal regulator design. In these methods, relative stability indicators are not specified, and in general assintotical approximations are make over the frequency domain transfer functions. Because of the complexity level of the switching power converters that are discrete circuits, many difficulties are encountered in the design and testing of these devices. In this paper, the authors propose a design procedure that uses the behavioral averaged PWM switch (BAPS) results and a computer program for the automatic generation of regulator prototypes, that make easy the theoretical design and simulation of closed-loop switching power converters.
