Problems solved by technology
When the power of the power supply increases, the current flowing through each switch arm also increases, resulting in an increase in the overall power loss at a square rate, making it difficult to apply the single-arm full-bridge HID switching power supply circuit scheme to high-power power supplies

The invention relates to a multi-interlaced direct-current HID switch power supply. An ignition output unit is connected to a first inductance unit and a second inductance unit. The first inductance unit is connected to a first interlaced bridge arm unit and simultaneously is connected to a current signal acquisition unit. The second inductance unit is connected to a second interlaced bridge arm unit and simultaneously is connected to the current signal acquisition unit. The current signal acquisition unit is connected to a signal acquisition unit. The first interlaced bridge arm unit is connected to the second interlaced bridge arm unit and is connected to an HVDC direct current input EMC unit. A primary signal interface unit is connected to a switch signal driving unit. The switch signaldriving unit is connected to the first interlaced bridge arm unit and the second interlaced bridge arm unit. The signal acquisition unit is connected to the primary signal interface unit. An existingsingle-bridge-arm full-bridge switch power supply circuit method is improved into a multi-interlaced bridge arm full bridge switch power supply circuit method so that power supply conversion efficiency of a large power application of a direct current HID switch power supply is effectively increased.
Description
technical field [0001] The present invention relates to a switching power supply, more particularly, to a multi-interleaved direct current HID switching power supply. Background technique [0002] The existing mainstream solution of DC HID switching power supply adopts a single bridge arm full-bridge switching power supply circuit solution. When the power of the power supply increases, the current flowing through each switching bridge arm also increases, resulting in an increase of the overall power loss at a square rate, making the full-bridge HID switching power supply circuit scheme of a single bridge arm difficult to apply to high-power power supplies . SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to overcome the defects of the prior art and provide a DC HID switching power supply with high power conversion efficiency for high-power applications. [0004] In order to achieve the above object, the present invention adopts a multi-interleav...
