  • Publication number: 20230283183
    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.

  • Publication number: 20230275448
    Abstract: A power supply controlling system is configured to supply power to a load and includes a first power supply device having a first outputting voltage and current to the load, a second power supply device having a second outputting voltage and current to the load, and a buck converter which is selectively connected to the first power supply device or the second power supply device first and is then connected in parallel with the power supply device without converter and the load. The buck converter is selectively connected to the power supply device with a higher voltage, and controls the output voltage of the converter to make it conform to the voltage of the other power supply device, so as to connect the two power supply devices in parallel and output current to the load.
