Abstract
Solar photovoltaic systems contribute to the development of the world's most environmentally sustainable and cost-effective electrical energy. High-power inverters commonly use a technique known as three-level design to increase their performance by soft-switching. On the other hand, the switching action is stressed in normal operation because the current or voltage will not be zero at the time of the transition. For CUK, SEPIC, ZETA and CASCODE converters operating in critical switch mode, it has been proposed that a new type of DC-DC converters primarily formed on capacitive coupling DC-DC converters be developed. The proposed converters are zero-current-voltage-switching half-square-quarter-wave converters with a zero-current auxiliary circuit. LC-circuit resonance causes power switches to turn on at zero voltage, getting rid of the switching losses during turn on. The hybrid Incremental Conductance & Integral Regulator technique is used to track MPP available from PV system. The proposed converter's results and efficiency are compared to those of traditional semi-square-quarter-wave zero-current-converter converters. The proposed converters achieved power efficiencies of 98.7% in the step-up mode and 98.8% in the step-down mode for the rated load state, respectively. The proposed CUK, SEPIC, ZETA and CASCODE Converters Simulation are implemented in the MATLAB Simulink programme to validate its efficiency.
