Abstract
A power supply system for outputting current to a load comprises a first power supply, a plurality of DC/DC converters connected to the first power supply in parallel, a second power source connected in parallel with the DC/DC converters and coupled to the load and a current sensor. The current sensor is configured between the first power supply and a low potential side of input terminals of the plurality of DC/DC converters, and the current sensor is configured for sensing a current information of the power supply system. When the power supply system outputs current to the load or the load can be charged back to the power supply system, the current sensor can measure the current information of each DC/DC converter through the current change of the switching states of the power switches inside the DC/DC converters, and has a simple circuit structure.
