Safety and reliability verification process of coil module in wireless power transfer system using circuit level sensitivity simulation

High-power wireless power transfer system (WPT) with high voltage and/or high current can be very dangerous to both engineers and consumers because the probability of explosion is much higher than that of low-power WPT system. Therefore, safety and reliability issues of a coil module in WPT systems should be verified before the actual experimental test. In this paper, a coil module verification process using a circuit level sensitivity simulation in the design stage will be proposed. The proposed verification process can be useful to the development of WPT systems with more safe and reliable coil modules.
