| Abstract |
Unlike the conventional battery-integrated LDC system, the distributed battery system can reduce the component cost by downsizing the LDC power supply, and balancing charge control method can improve battery utilization rate and lifetime, distributed LDC power supply development is progressing actively. n this paper, configuration of LDC power supply system is forward converter that can minimize the number of switch components and power supply size, it is applied to reduce loss caused by reset, which is a disadvantage of forward converter. It explains design of LDC power supply considering transformer temperature change according to switching frequency. A problem occurring in distributed control proposed a method to solve using Active Current Sharing method. the design of proposed high-efficiency forward converter and current distribution method were verified through experiment. |
