Resonant Network Analysis and Parameter Design of Bilateral LCCL Radio Energy Transmission System

This paper analyzes the characteristics and working principle of the double-sided LCCL resonant network in inductive wireless power transmission (ICPT ) technology. Based on this principle, a parameter design method of the double-sided LCCL resonant network combined with Ansoft 16.0 software is proposed. In the analysis, the single-turn coil is used to replace the multi-turn coil in the actual application, which simplifies the design process. This method can realize the constant output of the current of the transmitting coil at a specific frequency point and form a stable alternating magnetic field, which is not affected by the load and the coupling coefficient. A zero voltage switching-on ( ZVS ) method is proposed by adjusting the primary side compensation capacitor. A 10kw wireless power transmission prototype was designed to verify the feasibility and correctness of the proposed characteristics and parameters calculation method.
