Remote power distribution device architecture integrating multiple power supply conversion functions

Abstract

The invention discloses a remote power distribution device architecture integrating multiple power conversion functions. The device architecture comprises a power supply conversion module, an SSPC 28VDC module, an SSPC 115VAC module, an SSPC + / -270 V DC module, an SSPC + / -135 VDC module, an SSPC 28 VDC module and a COM communication module; the power supply conversion module is used for receivingan input power supply 230VAC and an input power supply 28VDC from the outside and converting the input power supply 230VAC and the input power supply 28VDC into an output power supply 230VAC, an output power supply 115VAC, an output power supply + / -270VDC, an output power supply + / -135VDC and an output power supply 28VDC. According to the remote power distribution device architecture integratingmultiple power conversion functions of the invention, after a new power supply framework is adopted, a plurality of original input power feeder lines of an RPDU are decreased to three, meanwhile, dueto the fact that the voltage class of the feeder lines is improved, input current can be reduced, the wire diameter of wires is reduced, and therefore, the weight of an airplane cable is reduced fromtwo dimensions.

Description

technical field [0001] The present invention relates to a remote power distribution device architecture integrating multiple power conversion functions. Background technique [0002] The power system of traditional aircraft (including more electric aircraft such as B787) includes four components: power generation, secondary power supply, primary power distribution and secondary power distribution. Among them, the generator is the primary power supply of the aircraft, usually 115VAC or 235VAC AC power supply, and the secondary power supply converts it into 28VDC for the primary power distribution bus bar, and then subdivides it into the secondary power distribution device by the primary power distribution system, and the latter supply power to the terminal load. [0003] Due to the introduction of the conversion device of the secondary power supply and the required intermediate link of primary power distribution, this system architecture leads to a complex system architectur...

Problems solved by technology

[0010] b. The SSPC output voltage is too single, only 115VAC and 28VDC can be output, which cannot meet the needs of future multi-electric aircraft for multiple voltage levels (+ / -135VDC, + / -270VDC);
