Research on Dual-LCC MCRWPT system based on controlled rectifier

Among many types of Wireless Power Transfer (WPT) technology, Magnetically Coupled Resonance Wireless Power Transfer (MCRWPT) technology has been studied more and more due to its stable transmission Power and strong antiinterference ability. In this paper, the operating characteristics of the Dual-LCC MCRWPT system based on the secondary side controlled rectifier are analyzed, and the variation of the system current with D, the phase relationship between the input voltage and current of the resonant network, the phase relationship between the output voltage and current of the resonant network, and the variation of the input and output load of the system are studied in depth. Through the simulation analysis of inverter MOSFET switching state, verify the effectiveness of the controlled rectifier control mode and the rationality of theoretical analysis, provide a solid theoretical basis for the optimization of the controlled rectifier control mode.
