Digital Signal Processor Based Design and Implementation of Fuzzy Control of Multi-Output Soft Switching Converter

Abstract

Due to the advantages like small size and less weigh of the power converters most of them are using the power converters for high power operations but in aerospace it is avoided to use high payloads. Soft switched quasi-resonant converter with the advantage like high frequency switching is designed to overcome the drawback of the switched converters. Also to overcome the drawbacks of frequency modulation control which requires wide band of frequency range, a new control technique which combines the advantages of inductor freewheeling and frequency modulation is proposed to operate wide range of load. Nowadays, in digital system voltage in the power supply is reduced and the board has different voltage components is present. Hence, in this work by considering all the above mentioned factors, an intelligent command by flyback multiple-output zero voltage switching-QRC is developed and presented using TMS320F2407A DSP. This converter is used in aerospace applications.
