Design of a DC battery DC energy storage power supply system with DVR
Abstract:Aiming at the demand of high-power DC energy storage power supply system in electromagnetic launcher, a design scheme of lithium battery energy storage power supply system with DVR is proposed. The lithium battery is used as the main energy storage medium, and the DVR module compensates the line impedance during large current discharge. The voltage drop generated by the internal resistance of the battery increases the system power density and energy utilization. The article introduces the overall structural design and key technologies of the system. Finally, the simulation and experimental platform tests verify the accuracy of the scheme and have a good dynamic response.
