PROBLEM TO BE SOLVED: To provide a power supply system and an energy storage system of the power supply system.SOLUTION: A first transformer transforms high voltage output from a first energy storage device of a power supply system, which is used to provide auxiliary power output, to a low voltage output from an auxiliary power output terminal, and includes a primary winding and an auxiliary winding. The primary winding is connected to the first energy storage device and a junction of a first switch and a second switch. A dotted terminal of the secondary winding is connected to the auxiliary power supply output via a first diode, and an opposite terminal thereof is connected to the earth. One end of a first capacitor is connected to the first diode cathode, and the other end of the first capacitor is connected to the earth. The power supply system of this invention is smaller, has a higher power density, and thus greatly reduces costs.SELECTED DRAWING: Figure 1 |
