Research on energy information integration method of DC-DC converter

To address the complexity of hardware required for communication between DC-DC converters, this study integrates power electronics and communication technologies to explore the information transmission capabilities of DC/DC converters. It aims to enable power electronic converters to simultaneously perform energy conversion and information transmission through an integrated approach to energy information. The study examines two power/data composite modulation techniques based on DC-DC converters. First, it analyzes the output voltage waveform of power PWM modulation carrying data and provides a binary frequency shift keying modulation and demodulation method. Then, it builds simulation platforms for each of the two composite modulation methods and conducts detailed simulations to verify their effectiveness. Finally, the simulation is completed using a synchronous buck converter. The results show that this method can achieve simultaneous energy conversion and information transmission without additional communication hardware, enabling deep interaction and integration of energy and information. This demonstrates the capability of power electronic converters to transmit information and validates the effectiveness of the proposed method.
