摘　　要：变流设备的广泛使用导致电力推进船舶电网大量谐波的产生和功率因数的降低。介绍两种治理谐波的主要措施——功率因数校正和多相整流技术,探讨了一种能提高功率因数的电力变流电路——高功率因数变流器,并对由移相电抗器构造的12脉波整流技术进行原理简述,给出了高功率因数三相无源变流器的电路拓扑结构与仿真模型。仿真结果表明,使用高功率因数变流器既能有效地抑制谐波又能提高功率因数。The application of power electronic technology in electric propulsive ship has caused massive harmonics and decreased the power factor. The paper summarized the power factor correction and the heterogeneity rectification technology, and discussed the high power factor converter, which can enhance the power factor. Also, the author illustrated the theories of 12 pulse heterogeneity rectification technology based on shifting reactors, and gave the rectification circuits and simulated models about passive power factor correction converter. The results of simulation showed that application of high power factor converter in electric propulsive ship system can suppress harmonies and enhance the power factor.
