Abstract

A power supply circuit module and a constant current output control system, the current output control system receives a predetermined power issued by a power supply unit, and supplies a certain current output power to a load, the system includes a plurality of power supply units The electrically connected branch power supply circuit is used to receive the predetermined power to output the power of a plurality of branch currents, and to collect the power of each branch current into the output power of the constant current and supply it to the load. When one of the branch power supply circuits is interrupted When outputting the power of the branch current, a main control integrated control signal will control the power supply unit to send out a redundant power so that the output power can be maintained at the constant current for output. The constant current output control system or power supply circuit module provided by the present invention can still maintain the output power at a constant current when some branch power supply circuits fail or must be cut off for maintenance.

Description

technical field [0001] The invention relates to a power output control system, in particular to a constant current power output control system. Background technique [0002] With the development and evolution of the current situation, electronic and electrical devices, equipment and systems have already unconsciously played an extremely important role in life. In order for these electronic and electrical equipment to operate normally, a stable power supply is the most indispensable condition. However, for certain electrical and electronic devices, equipment or systems, any interruption or instability of power supply is not allowed under certain circumstances. Especially for systems undergoing aging tests, on-line tests or real-time control, as long as there is a slight instability of power supply, it will cause a huge negative impact, not to mention the consequences of power supply interruption. Therefore, at the level of practical application, a power supply circuit modul...
