Fast Reduced Order Model of Low Frequency Integral Solver for Wireless Power Transfer System

A reduced order model of low frequency integral solver based on singular value decomposition is presented in this work. It can be easily utilized in analyzing the wireless power transfer system, even though the frequency as well as the distance between resonators and loops of WPT change simultaneously. The obtained numerical results show that the proposed reduced order model matches well with those results obtained by original low frequency integral solver.
