A Novel Single Micro Inverter Drived Dual Channal Synthesis Resonant Wireless Power Transfer System

In this paper, a multiport resonant single-input-dual-output system design scheme based on wireless energy transmission technology is proposed for DC microgrid systems. The topology adopts a single half-bridge inverter connected to a dual LC-LC coupled resonant network. Compared with the traditional multi-inverter scheme, the system complexity and cost are significantly reduced. Meanwhile, integration and space utilization are improved. An efficient energy supply for dual loads is realized. To ensure a resonant operating state, a resonant frequency tracking control strategy is introduced. The constant current output characteristics of the dual LC-LC network are revealed through theoretical analysis. Simulations and experiments verify the constant current characteristics and power regulation capability of the system. The results show that the proposed scheme has good flexibility and stability while ensuring efficient energy transfer. It provides a feasible solution for wireless energy transmission in DC microgrids.
