Problems solved by technology

[0003] However, in practical applications, the parallel power supply in the power supply device is directly connected to the load, and the change of the power supply voltage directly affects the voltage of the load. When there is a difference in the voltage of the parallel power supply, the power on and off of the power supply may cause the load to run unstable.
For example, the load is powered by the first battery pack, and the load runs stably. Now connect the second battery pack in parallel with the first battery pack. When the second battery pack is closed, due to the voltage difference between the second battery pack and the first battery pack, It may cause the load voltage to change, resulting in a decrease in the stability of the load operation

Abstract

The invention provides a power supply apparatus which comprises a first power supply, a first controller, a second power supply, a second controller and an adjusting circuit, wherein the positive electrode of the first power supply is connected in parallel with the positive electrode of the second power supply and then connected with the first end of a load, the negative electrode of the first power supply is respectively connected with the first end of the first controller and the adjusting circuit, the negative electrode of the second power supply is respectively connected with the first end of the second controller and the adjusting circuit, the second end of the first controller is connected in parallel with the second end of the second controller and then connected respectively with the second end of the load and the adjusting circuit, the second end of the load is connected with the adjusting circuit, and the adjusting circuit is used to adjust the voltage of the first power supply and the second power supply to control the voltage of the load. The power supply apparatus can improve the operation stability of a load.

Description

technical field [0001] The invention relates to the technical field of electronic circuits, in particular to a power supply device. Background technique [0002] The power supply device provides electric energy for the load, which is the guarantee for the normal operation of the load. In practical application scenarios, in order to ensure the safe operation of the load, the power supply device often includes multiple parallel-connected power supplies and a corresponding controller, and the controller controls the power supply to supply power to the load. [0003] However, in practical applications, the parallel power supply in the power supply device is directly connected to the load, and the change of the power supply voltage directly affects the voltage of the load. When there is a difference in the voltage of the parallel power supply, power on and off of the power supply may cause the load to run unstable. For example, the load is powered by the first battery pack, and ...
