Abstract

A fixing current output control system is provided, the current output the control system receives a reservation power sent by a power supplying unit and applies an output power of the current to a load. The system comprises a plurality of branch power supplying circuits connected to the power supplying unit to receive the power of the plurality of branch currents corresponding to the reservation power and then integrates the power of the branch currents as the output power of the fixing current to the load. When one of the branch powers supplying circuit is intermitted to output the power of the branch current, a main control integrated control signal will control the power supplying unit to send a redundant power to maintain the output power at the fixing current. The fixing current output control system or power supplying circuit module of this invention can still maintain the output power at the fixing current when patt of the branch power supplying circuit has faults or have to be cut off to repair.

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...
