Problems solved by technology
At present, the air-cooled heat dissipation equipment of high-power switching power supply is generally an external power supply, which not only brings trouble to operation, but also causes confusion on site due to too many devices or lines on site.
In a multi-output power supply, especially a power supply with 4 or more isolated outputs, it is generally composed of DC-DC converters directly, so that the efficiency of the whole machine is not high, the cost is large, and the maintenance cost is high. It limits the usability of the power supply in some occasions

The input end of the three-phase filter is connected with an alternating-current source, the output end of the three-phase filter is connected with the input end of an input rectifying and power factor correcting circuit, the output end of the input rectifying and power factor correcting circuit is connected with the input end of a 48 V control protection circuit and the input end of a 48 V circuit main power conversion circuit respectively, the output end of the 48 V circuit main power conversion circuit is connected with the input end of a 48 V secondary output rectifying and filtering circuit, and the driving end of the 48 V control protection circuit is connected with the input end of the 48 V circuit main power conversion circuit and the output end of the secondary output rectifying and filtering circuit respectively. The high-power power source is provided with four outputs which are mutually isolated and cannot interfere with one another and is wide in application range.
Description
[0001] technical field [0002] The invention relates to the field of switching power supplies, in particular to an air-cooled multi-channel output high-power power supply. [0003] Background technique [0004] In the design of the switching power supply, the operating environment of the power supply should be fully considered. With the development of the power supply, the switching power supply is often required to be designed with a multi-channel output function. At present, the air-cooled heat dissipation equipment of high-power switching power supply is generally an external power supply, which not only brings trouble to operation, but also causes confusion on site due to too many devices or lines on site. In a multi-output power supply, especially a power supply with 4 or more isolated outputs, it is generally composed of DC-DC converters directly, so that the efficiency of the whole machine is not high, the cost is large, and the maintenance cost is high.
