Abstract: Power quality plays an important role in the effective functioning of the utilities. Power Factor Correction (PFC) is an important area of research, where considerable attention has to be paid. Modern day world should be energy conservative since, it is necessary to provide some resources for the future. The techniques discussed in the present work includes, analysis of various techniques for power factor correction and harmonic elimination in the power electronic converters. The performance of a Direct Current (DC) to DC converter based upon the Compound Active Clamp (CAC) technique has been analyzed in the present work. The converter performance is observed under both open loop and closed loop conditions for various load conditions. The configuration of the converter considered in the present work is interleaved Two Inductor Boost (TIB) converter. The performance of the TIB and CAC boost converter are considered in the present research work. The relationship between input voltage and output voltage, input voltage and input power, input power and output power were plotted and interpreted. The results emphasize that the two inductor boost converter had a superior performance over the compound active clamping boost converter in terms of output voltage. The harmonics which are present in the output voltage of the PWM AC chopper is eliminated with the application of evolutionary algorithm technique namely Differential Evolution (DE). The DE technique is applied to optimize the firing angles of the PWM AC choppers. The optimized firing angles of the switches in the PWM AC choppers will lead to the elimination of harmonics in the output voltage. The task was performed with the help of the code written in MATLAB m file. The simulation was carried out for the open loop and closed loop operation of the PWM AC chopper using MATLAB/Simulink. The hardware model was developed for the closed loop operation of the PWM AC chopper and its output waveforms are measured. The results are validated through publications. newline
