A high-voltage rectification system for power supply to a machine room comprises a first phase-shift step-down transformer, a second phase-shift step-down transformer, a first rectification cabinet, a second rectification cabinet, a third rectification cabinet and a fourth rectification cabinet, wherein the first phase-shift step-down transformer and the second phase-shift step-down transformer are used for receiving an initial high-voltage three-phase AC current and carrying out voltage reduction on the initial high-voltage three-phase AC current; the first phase-shift step-down transformer is used for making the initial high-voltage three-phase AC current shifted backwards at a first predetermined phase so that the obtained first phase-shift step-down AC voltage is transmitted to the first rectification cabinet, and making the initial high-voltage three-phase AC current shifted forwards at a second predetermined phase so that the obtained second phase-shift step-down AC voltage is transmitted to the second rectification cabinet; the second phase-shift step-down transformer is used for making the initial high-voltage three-phase AC current shifted forwards at a third predetermined phase so that the obtained third phase-shift step-down AC voltage is transmitted to the third rectification cabinet, and making the initial high-voltage three-phase AC current shifted forwards at a fourth predetermined phase so that the obtained fourth phase-shift step-down AC current is transmitted to the fourth rectification cabinet; and the first rectification cabinet, the second rectification cabinet, the third rectification cabinet and the fourth rectification cabinet are used for respectively rectifying the first phase-shift step-down AC current, the second phase-shift step-down AC current, the third phase-shift step-down AC current and the fourth phase-shift step-down AC current so as to provide DC current for a load.
Description
technical field [0001] The invention relates to the fields of computer technology and power supply technology, and more specifically, the invention relates to a high-voltage rectification system used for power supply in a computer room. Background technique [0002] At present, data centers are developing rapidly in China. In order to reduce the power conversion link of the data center power supply system and improve energy utilization, many data center projects have begun to try to use DC power systems to power IT equipment, that is, 220V mains power is rectified and stabilized by DC power systems. After pressing, power is supplied to IT equipment. However, most of the current DC power supply systems adopt a two-stage conversion mode, which has a complex structure and low efficiency, and cannot better reflect the advantages of the DC power supply system. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a high-vo...
