A wireless power transfer (WPT) system usually needs dual-side cooperated control for efficiency optimization and power regulation, which requires the establishment of a wireless communication link between the transmitter and the receiver. Phase shift keying (PSK) communication is a good choice for WPT systems because of its advantages of high security and low hardware cost. However, the converter phase modulation required by the PSK communication will cause output power and voltage fluctuations. The relationship between the phase modulation depth and output fluctuation amplitude is analyzed. Then, a pulse density modulation-based feedforward power compensation method is put forward to compensate for the output voltage fluctuations caused by the PSK communication. Experimental results show that the proposed power compensator can suppress the output voltage fluctuations to an insignificant level without a large output filter capacitor, indicating that the proposed method overcomes the main drawback of PSK communication in WPT systems.
