An Integrated Single-Phase to Three-Phase Wireless AC Motor Drive System Connected to Class-E/F₃ Inverter and S-S Resonance Compensation Circuit

This paper introduces a wireless AC motor drive system operating in a single-stage/single-phase to three-phase configuration. The transmitter (Tx) employs a Class-E/F<inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">3</inf> resonant inverter design, which effectively reduces switching current and voltage stress, thereby amplifying output power and enhancing reliability. The receiver (Rx) utilizes a novel wireless AC motor drive topology capable of directly converting singlephase AC power to three-phase AC output, efficiently powering AC motors. Numerical analysis demonstrates that the proposed system achieves a power transfer efficiency of 94.39%.
