Electromagnetic Interference on Analog-To-Digital Converters from High-Power Wireless Power Transfer System for Automotive Charger

Abstract

Wireless power transfer (WPT) technologies have been actively studied for electric vehicle (EV) battery charging applications. Electromagnetic radiated emissions from high-power WPT system are substantial, and its effects on an analog circuits cannot be ignored. In this paper, we investigated the electromagnetic interference (EMI) on analog-to-digital converters (ADCs) from high-power WPT system for the automotive charger. A 3-kW-class high-power WPT system for compact EV operating at 20 kHz was designed and validated via simulation results. An ADC chip was designed to analyze the effects of EMI from high power WPT system. Based on simulation results, we verified that the performance degradation of the ADC connected through a cable due to the coupled noise from high power WPT system.
