Characteristic Analysis of Dual-Load Inductively Coupled Power Transfer System Based on LCC-S

摘要

Inductively coupled power transfer (ICPT) system is of great significance to the synchronous power supply of multiple loads. In a dual-load system, the output characteristics of load #1 will be affected when load #2 enters the track. In this paper, the output characteristics of the LCC-S system under single-load and dual-load modes are analyzed, and the effect on the output power of load #1 as load #2 enters the track is discussed. The equivalent circuit and mathematical model of the dual-load system are established, and the load #1 output power and the overall transmission efficiency of the system in the dual-load mode are analyzed using MATLAB simulation. The conclusions can be obtained that the small resistance of load #2 makes small influence on output power of load 1, but when load #2 is a larger resistance, the output power of load 1 is almost unchanged. In particular, the efficiency of the system increases and the track current is almost constant with the load #2 enters the track.
