secondly, connecting the power supply module with a copper bar through screws, wherein the copper bar is a 48V direct current power supply copper bar;
and thirdly, directly inserting each node needing power supply in the cabinet on the copper bar through a power supply terminal to obtain power.
The AC/DC converter is internally provided with a PFC boost converter and a DC/DC conversion module, and the voltage conversion process comprises the following steps: 220V commercial power is converted into 380V direct current through a rectification and PFC boost converter, and then the 380V direct current is converted into 48V direct current through a DC/DC conversion module.
The power module adopts a power module with the efficiency of at least 94 percent, and the power module adopts an N + N redundant power supply mode.
Example (b): the 220V commercial power of the general prior art is converted into +12V direct current through AC/DC, and the +12V direct current is connected with a power supply copper bar; and each node of the power taking end directly takes +12V power on the copper bar.
In the invention, 220V commercial power is converted into +48V direct current through AC/DC, and the +48V direct current is connected with a power supply copper bar; and each node of the power taking end directly takes +48V power on the copper bar.
The comparison of the two power supply modes is as follows, wherein a is the prior art, and b is the invention:
namely:
wherein,
conduction losses for power supply architectures employing prior art techniques;
conducting voltage for a power supply copper bar: + 12V;
From the above analysis results, it can be seen that at the same load power:
the power supply structure can greatly reduce the conduction loss of the cabinet system, thereby being beneficial to reducing the energy consumption of the system.
The technical features described in the specification are well known to those skilled in the art.
