Description of drawings
Accompanying drawing 1 is the structured flowchart of the utility model.
Mark in the accompanying drawing is represented respectively:
1, flow equalizing circuit module, 2, voltage-regulating circuit, 3, overcurrent circuit protection module, 4, the CPCI power interface.
Embodiment
Below in conjunction with accompanying drawing a kind of CPCI interface power panel with redundancy feature of the utility model is done following the detailed description.
Shown in accompanying drawing 1, this a kind of CPCI interface power panel with redundancy feature, its structure comprises CPCI power interface 4, CPCI power interface 4 is AN connectors of a kind of 47 pins, is used for I/O power and signal interface.Said CPCI power interface 4 is connected with voltage-regulating circuit 2; This voltage-regulating circuit 2 comprises 12V voltage-regulating circuit, 5V voltage-regulating circuit and 3.3V voltage-regulating circuit, 5VSB voltage-regulating circuit; Above-mentioned voltage-regulating circuit 2 is connected with flow equalizing circuit module 1, overcurrent circuit protection module 3, and said voltage-regulating circuit 2, flow equalizing circuit module 1, overcurrent circuit protection module 3 are through external input direct voltage.
The electric current of exporting when flow equalizing circuit module 1 guarantees two-way power supply operate as normal is balanced; To the contribution of load about equally; Avoided the waste of redundant circuit module, when having guaranteed that again main circuit breaks down simultaneously, redundant module can fast, normally replace main circuit work.
The current feedback of each road power supply of design consideration of overcurrent circuit protection module 3 is carried out overcurrent monitoring, and if any over-current phenomenon avoidance, the input of can cutting off the electricity supply automatically of overcurrent circuit protection module avoids the components and parts in the circuit to damage because of electric current is excessive.
The direct voltage of said input is 20V-40V.
When the main circuit operate as normal, the redundant module circuit that increases is operate as normal also; When main circuit work was undesired, the redundant module circuit was born the work of faulty circuit, reduced fault time, had improved the reliability and stability of power panel.
