Abstract

A method of modelling DC-DC converters has been developed using SIMULINK. For flyback quasi-resonant converter (QRC), the equations for the state variables and the active and passive switches have been derived and a corresponding SIMULINK model has been constructed. Sub-models for the different parts of the controller have also been constructed, and the complete system has been simulated. This modelling technique requires less memory and CPU time than SPICE. 1 Introduction In many industrial applications, there is an increasing demand to reduce the size and weight of power supply circuits and to improve their efficiency. With advances in semiconductor devices (
