Analysis of EMF Noise from the Receiving Coil Topologies for Wireless Power Transfer

Abstract

Electromagnetic-field (EMF) noise from the only coil system with CSSR (Current source, Series resonance for TX, Series resonance for RX, and Resistive load) and CSPR (Current source, Series resonance for TX, Parallel resonance for RX, and Resistive load) topologies are featured in this paper. Wireless power transfer (WPT) system for a monitor is designed and analysed by using the equivalent circuit model. Most of the characteristic of CSSR and CSPR topologies seem similar to each other except for the current through receiving coil. EMF noise from CSSR topology is very similar to that of CSPR topology under the condition of maximum power transmission. However, when transferred power is decreased, EMF noise is decreased at only CSSR topology. Therefore, EMF noise point of view, CSSR topology is advantageous than CSPR topology.
