Electrostatic discharge (ESD) effects on wireless power transfer using magnetic resonance coupling

Abstract

In this paper, we present the analysis of electrostatic discharge (ESD) effects in wireless power transfer (WPT) using magnetic resonance coupling. For analyzing ESD effects, we use the simple equivalent circuit model which consists of self-inductance, mutual inductance, parasitic resistance, and capacitance. The ESD pulse is generated by the model of an ESD generator. The generated ESD pulse is injected to the source coil and the transferred ESD pulse is obtained in the time-domain. In addition, the transferred ESD pulse is analyzed in the frequency-domain. We compare the resonant frequency of the WPT system with the frequency of the transferred ESD pulse, and analyze the relationship between the two frequencies.
