Abstract

The paper concerns modeling the nonisothermal characteristics of switch-mode voltage regulators (VRs) consisting of the boost converter with discrete semiconductor devices and a monolithic current-mode pulsewidth modulation controller. New electrothermal hybrid models of a p-n diode and a power metal oxide semiconductor transistor, as well as the electrothermal model of the monolithic UC3842 controller dedicated for SPICE analysis of switch-mode VRs are presented and described in detail. The results of simulations verified experimentally are given as well.
