M-ary Amplitude Shift Keying Power and Information Synchronous Transmission Based on Phase-Shifted Full-Bridge

This paper proposes an M-ary amplitude shift keying (MASK) power and information synchronous transmission system based on phase-shifted full-bridge (PSFB) for applications in wireless (WPT). The Pulse Width Modulation (PWM) waveform uses different phases to control the MOSFET inverter MASK modulation. voltage generates M transformation, forming a comprehensive flow. demodulation circuit processes transmitted secondary side, following supply with differential amplifier, realize of information. Compared conventional modulation, system’s volume is significantly reduced, DC-DC modulation has no filtering effect. It transmits high-level data improves rate from perspective bit width. In experiment, 16-bit width are transmitted, increased by four times compared Combined DSP, designed reduces fluctuation at receiving end 5% minimizes impact system.
