| description | Aiming at the problems of complex structure, energy signal crosstalk, limited transmission bit width, low transmission rate and the like in a signal transmission technology in a wireless power transmission (WPT) system, the invention provides an M-ary amplitude shift keying (MASK) energy and signal simultaneous transmission system based on a phase-shifted full bridge (PSFB), PWM waves of different phases are generated through a DSP and are added to a control end of an MOSEFT tube in a full-bridge inverter, MASK modulation is performed, and the signal transmission rate is improved. The inversion voltage generates M kinds of amplitude transformation. And the signal is transmitted to the secondary side along with the electric energy, processed by a designed demodulation circuit and input to the DSP for restoration, so that simultaneous transmission of energy and information is realized. Compared with a traditional amplitude modulation method, the size of the system is reduced, influences of filtering of a DC-DC |
