摘要：
In distributed DC power systems (DC-DPSs), the communication stability between different devices is critical for system control. In this paper, a new data modulation strategy is proposed for achieving mutual communication between different LLC resonant converters in DC-DPSs. This strategy modulates the data into the switching frequency of the LLC resonant converter and sends it when the LLC resonant converter converts power, eliminating the need for extra wiring and coupling units. Furthermore, this paper employs the 2DPSK demodulation scheme, which reduces bit error rate when compared to the PSK scheme. Finally, a DC-DPS composed of two LLC resonant converters is built in this paper, and the theory's correctness is validated through simulation.
