Comparative Analysis of High Efficiency Converter Techniques

Abstract

Recently, several analysis works has been designed for improving the efficiency of DC-DC convertor for high output power. But, multilevel DC-DC boost convertor fails to attain higher power conversion efficiency based on switching losses. In existing boost converters, MPPT algorithm provides unbalanced current for lower parasitic resistance and capacitance. By using individual soft-switching circuit in PWM results with higher cost and shows complexity of the circuit. While providing higher cost and complex circuit, boost converter has additional current and voltage stress. To improve the efficiency of DC-DC converter, a Bayes Soft switch Interleaved Boost convertor (BSS-IBC) structure is intended. To reduce the convertor switch time and improve the output voltage and current, an integrated structure of sliding window and Pulse width Modulation (SW-PWM) is developed. To cut back the switch noise and switch time, projected IBI-SW primarily based PWM structure.
