基于无源电压纹波注入的24脉航空交直流变换器
24-pulse aviation AC-DC converter based on passive voltage ripple injection
摘要
Abstract
With the goal of solving the problem of high harmonic content of the current at the input side of aviation linear alternating current and direct current(AC-DC)conversion topology,this paper proposes a multipulse avia-tion transformer rectifier unit(TRU)based on passive voltage ripple injection unit.The unit consists of 12-pulse transformers,two groups of rectifier bridges,an interphase reactor(IPR),and a passive voltage ripple injection unit(PVRI unit).Combining the PVRI and IPR units,the topology realized 24-pulse DC output by using 12-pulse transformers and two groups of rectifier bridges.Based on the polarity of ripple voltage,this paper describes in de-tail the process of forming a new output voltage vector by alternately adjusting the amplitude of the output voltage vectors of two groups of rectifier bridges in equal proportion,thus forming a new output voltage vector and achieving pulse multiplication.Related expressions were also derived.The working mode,equivalent capacity,and harmonic content of the proposed TRU were also analyzed in detail in this paper.Finally,the prototype was developed,and the feasibility and correctness of the topology were verified by experimental research.关键词
