POWER GENERATING SYSTEM AND ENERGY STORAGE SYSTEM

This invention has opened up the power system and energy storage system of the power supply system. The power supply system 100 is used to provide auxiliary power output and includes a first energy storage device 11, a first inverter 21 coupled to the first energy storage device 11, a first transformer T1, a first diode D1 and a capacitor C1. The first inverter 21 includes a first switch S1 and second switch S2 in series. The first transformer transforms high voltage from the first energy storage device to the low voltage output from auxiliary power output terminal, and includes the primary winding and auxiliary winding. The primary winding is connected to the first energy storage device11 and the junction of the first and second switch S1,S2, and the homonymous terminal of the secondary winding is connected to the auxiliary power output through the first diode, with the synonymous terminal connected to the earth. One end of the first capacitor is connected to the first diode cathode and the other end is connected to the earth. The power supply of this invention is smaller and has a higher power density, greatly reducing costs.
