Feedback Control of an Interleaved Buck Converter with Improved Conversion Ratio

Abstract: Proposed Interleaved Buck Converter (IBC) which has a continuous input current, high step down conversion ratio, extremely low output current ripple. The proposed converter can provide current sharing control method. These benefits can be obtained without any additional stress on the circuit components. Proposed converter is suitable for high power application and operating duty cycle is below 50%.The feedback loop is used for the proposed buck converter to produce constant output voltage. The feedback loop control is given using PI control. Simulation is carried out with MATLAB and results are obtained. Keywords: Interleaved Buck Converter, Improved Conversion Ratio, Feedback Control.
