Abstract

The invention relates to a current sharing circuit of a parallel power supply, a power supply module and an integrated circuit test system. The current sharing circuit of the parallel power supply comprises a master direct-current power supply module, a slave direct-current (DC) power supply module, a master current detection module and a slave current detection module, the slave DC power supply module comprises a slave current adjusting unit; the input end of the main current detection module is electrically connected to the output end of the main DC power supply module, and the output end ofthe main current detection module is electrically connected to the first input end of the slave current adjustment unit; the input end of the slave current detection module is electrically connectedto the output end of the slave DC power supply module, and the output end of the slave current detection module is electrically connected to the second input end of the slave current adjustment unit;and the slave current adjusting unit is used for adjusting the output current of the slave DC power supply module according to the current difference value between the current value detected by the master current detection module and the current value detected by the slave current detection module. According to the invention, the power loss of the parallel power supply is reduced.

Description

Technical field [0001] This application relates to the field of current sharing of power supplies, and in particular to a current sharing circuit of parallel power supplies, power modules and integrated circuit test systems. Background technique [0002] With the development and application of power electronic technology, the power supply system has higher and higher requirements for high-power power systems. In the actual application process, the output power and reliability of a single DC power supply cannot meet user requirements. Once a single power supply fails , The power supply system fails to operate. Parallel operation of multiple power modules can meet different output power requirements, and its capacity can be flexibly expanded according to actual needs, and it is easy to realize the redundancy of the power system. After a module is damaged, the output of the entire power system still has enough load capacity to improve Improve the reliability of the power supply sys...
