With the advancement of electric vehicles and energy storage devices, power conversion devices capable of charging and managing high-voltage batteries and facilitating real-time communication are becoming increasingly important. However, existing communication techniques require separate transceiver devices, and security issues arise with communication data. Meanwhile, electromagnetic interference (EMI) generated by the high-speed switching of the power conversion devices not only causes their operating problems but also degrades communication reliability. Additionally, EMI filters used to mitigate EMI increase the cost and volume of the power conversion system. This study proposes talkative power conversion, which enables communication by inserting specific data into the input/output voltage and current ripples of power conversion devices, to perform communication functions without any need for separate transceiver devices using an input-parallel output-series (IPOS)-LLC converter for high-voltage applications. The proposed IPOS-LLC converter suppresses electromagnetic (EM) noises via spread spectrum modulation. It generates output voltage ripples using a multi-spread phase shift keying technique, which adjusts the phase between power conversion modules to utilize them for communication. The EM noise reduction performance and communication functionality of the proposed IPOS-LLC converter are experimentally verified using a l kW prototype.
