Research on a DC-DC Energy Router in Microgrid

As a distributed energy system, the core of microgrid is to realize efficient management and flexible distribution of energy. A microgrid topology based on DC-DC energy routers is proposed and its potential advantages in improving the efficiency and stability of microgrids are discussed. The driving waveform and voltage output waveform of power electronic switching tube of high frequency inverter and single phase full wave rectifier in DC- DC converter are analyzed. Through the comparison and analysis of the data obtained by changing the duty cycle of the PWM drive waveform, the experimental results show that by properly adjusting the PWM waveform, when the duty cycle is 0.08 and 0.4, the output voltage of the DC-DC energy router can be adjusted, so as to meet the requirements of different loads in the microgrid and improve the efficiency of the DC-DC energy router. This research expands the application of DC-DC energy router in microgrid and provides a new idea and method for microgrid energy management. Future work will further explore the performance of DC-DC energy routers in different scenarios and optimize their design to adapt to a wider range of application scenarios.
