Abstract Switching ripple initiated by power electronic circuits can be modulated to transmit data, which is a method for electronic equipment to be networked. The principle of data communication based on switching ripple modulation, as well as the method that can realize switching ripple modulation without affecting power conversion, are presented in this paper. For distributed Boost circuits with parallel input, the ripple signal model of the power circuits is analyzed, and the frequency shift keying(FSK) communication system based on ripple modulation is realized by experiment. This technology embeds data transmission mechanism into power conversion circuit, and is a cost-effective way to realize power line communication.

Key words： Switching ripple power line communication power electronic circuits frequency shift keying(FSK)
