Design of MISO Wireless Power Transfer System for Electric Vehicle in Optimal Efficiency

Wireless power transfer (WPT) technology is an advanced and innovative method of transmitting electrical energy, which has garnered widespread interest and research. Compared to single-input-single-output (SISO) system, multi-input-single-output (MISO) system configuration in wireless power transfer offers significant advantages. It provides a broader magnetic field distribution, higher system resilience to misalignment, increased power transmission capacity, and greater design flexibility. This paper designed and analyzed a MISO wireless power transfer system, deduced the influence of cross-coupling, output characteristics and optimal efficiency operating conditions. A simulation model is developed to validate the conclusions drawn, and an experiment is designed to verify the conclusion.
