Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides a DC / DC power supply module current sharing control device, which solves the problem that the existing heat dissipation device continuously performs cooling operations on the current sharing controller. When the ambient temperature is low, the current sharing controller When there is less heat generated, there is no need for a cooling device to work, and due to the poor sealing of the device due to the installed cooling device, it is easy to enter dust during storage and damage the internal circuit.

Description

technical field [0001] The invention relates to the technical field of current sharing control, in particular to a current sharing control device of a DC / DC power supply module. Background technique [0002] Since the parameters of each parallel power supply module cannot be completely consistent, if the modules are directly connected in parallel, it is bound to be difficult to ensure that each module will share the load current evenly, which will cause the problem of current imbalance. The main reason for adopting current sharing control is that the main reason why the parallel operation of modules requires current sharing control is because the module The output is a voltage source, and a small deviation in the output voltage will cause a large difference in the output current. The currently used current sharing controllers, especially the current sharing controllers integrated with large equipment, will gradually generate heat during use. The existing heat dissipation de...
