Design of low EMI and low weight tightly-coupled resonant magnetic field handheld charger (TCR-MFHC) for electric vehicle

Abstract

Recently, the significant growth of the electric vehicle market led to a rapid increase in the number of electric vehicle charger sales. A tightly coupled resonant magnetic induced charging system will be a promising charging method for electric vehicle because it has a lot of advantages to electrically safe, not influenced by climate and dust and durable. However, this method has issues that magnetic field from coils in this method can cause negative effects on human body and influence another devices. In this thesis, the charger structure for low weight and low electromagnetic field and input impedance design of the charging system for low electromagnetic interference based on analysis of a resonant split phenomenon is proposed. We design the tightly coupled resonant magnetic induced charging system for electric vehicle based on proposed methods. The proposed methods is verified by simulation tool.
