Abstract

The invention relates to a high-power-density onboard variable voltage rectifier, which comprises an input connector, an input filter unit, a pulse transformator, a rectifying unit, an output filter unit, a heat radiation unit, a fault warning unit, an output connector and a casing, wherein the casing consists of a bottom plate, a panel and a cover hoop. Compared with an independent voltage stabilizing circuit, the high-power-density onboard variable voltage rectifier has the advantages that the device number is decreased, the system complexity is reduced, the system reliability is improved, and characteristics of low input current harmonic waves, stable output voltage and the like are realized. The high-power-density onboard variable voltage rectifier is suitable for being applied to middle-high-power rectifying occasions in aviation industry and national production.

Description

technical field [0001] The invention relates to a transformer rectifier, in particular to a high power density airborne transformer rectifier. Background technique [0002] With the continuous improvement of installation requirements, the requirements for the volume, weight and reliability of airborne equipment are also getting higher and higher. The existing airborne transformer rectifiers generally have a large volume and weight, occupying installation space, increasing the overall burden of the equipment, inconvenient maintenance, and unable to meet the needs of modern installations. Traditional transformers are used on ordinary ferrite cores, wound with enameled wires or multi-strand wires. The volume is relatively large, and the transfer efficiency is not enough, which limits the scope of use of the transformer and limits the minimum size that the power system can achieve. Contents of the invention [0003] In order to solve the shortcomings of traditional transforme...
