摘要

Compensation mode has an important influence on the efficiency and power characteristics of contactless charging system. Analyze the necessary of power compensation for the loosely coupled transformer based on electromagnetic inductive contactless charging system structure of electric vehicle. By analyzing the four kinds of compensation models, the S/S model is selected due to its high system efficiency and easy control, and the matching relationship between the system frequency and the equivalent load is put forward. In the premise of considering the system efficiency and the user experience, the efficiency-preferred operating frequency selection strategy of the electric vehicle electromagnetic inductive contactless charging system is proposed, which contributes to produce a new idea to maintain the system to work efficiently by the operating frequency adjusting. The correctness of the analysis and optimization strategy is verified by examples.
