Abstract

Twelve fourth-order PWM DC/DC power converters with limited duty cycle range are treated and a survey of important data (maximum voltage and current ratings for the elements, RMS values for the semiconductor devices and a rough approximation of the losses) of the circuits are given to help to decide whether a given topology is interesting for realization. Furthermore, idealized power converter models based on duty ratio averaging are established in which continuous operation mode and ideal devices are assumed. Finally, dimensioning equations for the inductors and the capacitors are given. The results make it possible to estimate the applicability of given power converter structures and offer sufficient material for the calculation and analysis of these circuits
