A Power Line Communication Method for SRG with Modified C-Dump Power Converter

Switched reluctance generator (SRG) have unavoidable application potential in power generation because of good high reliability, simple structure, high fault tolerance, and therefore attract increasing research attentions. Due to the intelligentization demands, reliable communication is of great significance for fault monitoring and remote control among power converters integrated in microgrid systems. In this paper, an improved new SRG power converter is discussed, which is able to reduce the number of switching devices, as well as the cost of SRG system. The power and signal synchronous transmission (PSST) is also realized by using the modified power converter without requirement of extra coupling equipment. The signals are embedded by modulating the output voltage ripples and FFT method is adopted on the receiver side to demodulate the signals. Simulation verification are carried out to confirm the feasibilities of the proposed converter and power line communication method.
