Abstract

Ten half-bridge (seven fourth order and three second order as reference) PWM DC/DC converters 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. Furthermore, realistic converter models with simple device-models based on duty ratio averaging are established. Finally, dimensioning equations for the inductors and the capacitors are given. The results make it possible to estimate the applicability of the given converter structures and offer sufficient material for the calculation and analysis of these circuits
