Abstract
Variable switching frequency current controller based integrated power factor corrected switched mode power converter for class C and class D appliances has been designed and analyzed in this work. Proposed integrated converter offers low current stress on the switch. Variable switching frequency current controller has been selected owing to its features, viz – fast dynamic response, no compensation circuit and less complexity in design. Integrated converter for 100 W load operating in universal range of voltage (90 V–230 V), 50 Hz has been designed and implemented using MATLAB/Simulink, results of this converter comply with international regulatory standards (IEC 6100-3-2 and IEEE 519-1992). Experimental results conform and validate the analysis.
