摘要
航空用直流电一般由恒/变频交流电经整流器获取,整流器本身及其负载的非线性,会导致交流电网产生大量谐波,降低系统功率因数。本文针对航空用某电力变换器中不控整流桥对交流电网产生的严重谐波污染问题,展开改进方案研究。从谐波抑制方面对比了几种常见整流器性能,提出一种航空用高功率因数可控升压整流器,通过分析其电路原理,并从仿真层面验证了可控升压整流器在谐波抑制、高功率因数、直流输出可灵活调整等方面的优越性。
The DC power used in aviation, generally obtained by the constant frequence AC rectifier, non-line of the converter itself and the load, causing much humorous on the AC power, reducing the power factor. In this paper, an improved scheme is studied for the serious harmonic pollution casued by the non controlled recitifier bridge in a power converter, compared with the performance of several kinds of rectifier, a high power factor controlled rectifier is proposed, analyzed the principle of the circuit, and from the simulation level proving the advantages of controlled recitifier in the aspects of harmonic suppression, high power factor, DC output can be adjusted flexibly and so on.
