ABSTRACT:
A distributed power system, wherein a backup boost transformer is connected between a PFC transformer and a FE DC transformer. The backup boost transformer is also parallel connected with a diode. The backup boost transformer only operates in the sustaining time, if the first DC voltage drops gradually, the backup boost transformer will increase this first DC voltage and stabilize it at a preset voltage of the FE DC transformer. Therefore, the capacity of the storage capacitor of the PFC transformer can be fully utilized to have a longer sustaining time and decrease the variation range of the second DC voltage so as to enhance the efficiency and power density thereof.
