Study and Analysis of Different Compensation Circuits for PV Integrated Wireless Power Transmission

Electrical engineering can undergo a significant transformation with the use of wireless power transfer, which does away with the need for traditional copper connections and current-carrying wires. Hence, Wireless Power Transmission (WPT) for short-range distances has gained attention in recent times. For WPT, radiative and non-radiative methods are used, whereas the non-radiative method uses inductive wireless power transmission mode. This mode results in a decrease in the efficiency of the system, for which compensation circuits are used. However, the selection of a proper compensation circuit needs considerable attention, as there are four types of compensation circuits: series-series, series-parallel, parallel-series, and parallel-parallel. In this research work, a PV integration WPT model is proposed for household applications in contrast to the traditional AC-supplied WPT system. The four types of compensation circuits are analyzed and compared for the proposed model based on the output current, output voltage, and output power. Whereas the model was implemented in SimulinkIMATLAB. It was observed that the parallel-parallel compensation circuit resulted in higher values of output voltage, output current, and output power as compared to other circuits.
