A modular server power supply with multi-output combination

Abstract

The invention discloses a multi-output combined modular server power supply, which includes a first power supply module and a second power supply module, the first power supply module and the second power supply module are connected through a connector, and the first power supply module includes an EMI circuit unit , rectifier module, PFC conversion module, PFC switch mos drive module; the second power supply module includes DC / DC conversion module, SR module, output filter module, SC drive unit, the working principle of the present invention is simple, and the novel modular combined power supply module can It is more flexible to use according to the output requirements, avoiding the waste of research and development resources. If there is a repair or scrap caused by a power failure, it can be processed in modules to reduce maintenance costs.

Description

technical field [0001] The invention relates to the technical field of power supplies, in particular to a multi-output combined modular server power supply. Background technique [0002] At present, most of the common power supply modules in the general server market adopt the CRPS power supply defined by the industry standard. This kind of power supply is accepted by various server manufacturers because of its standard size structure and standardized output pin definition, and it is also important for power supply development suppliers. It has good versatility. Power supply development is based on a standard platform to develop a power supply that can be compatible with the needs of various server manufacturers, thereby increasing the number of shipments and improving product cost competitiveness. At present, CRPS power supplies on the market are mainly divided into two standard sizes: 185mm* Standard 185-size CRPS with a length, width and height of 73.5mm*40mm, and standar...

Problems solved by technology

[0004] At present, the input of CRPS power supply modules is generally compatible with 230Vac / 270Vdc input, but due to the difference in output voltage, the same power section needs to develop a variety of power supply modules in order to meet the needs of different output voltages; in terms of development resource investment, if a family If power supply developers want to meet the CRPS requirements of the full power supply product line, they must develop at least dozens of power modules to meet customer needs. This is a great test for R&D resource investment and R&D cost control. This development and production model requires a huge amount of input for suppliers. From the perspective of technology development, it is found that the input specifications of the power supply are the same, and a total of two-stage energy conversion is required from input to output. Power supplies with different output voltages The difference in specifications is mainly in the second-stage power conversion. In order to meet the change of output voltage, the first-stage power conversion part must be redesigned to waste R&D resources.
