【摘要】 电子技术快速发展,非线性电子元器件在船舶电力推进电机中得到大量使用,对电网造成了严重的谐波污染。在船舶电网系统中,随着变频器容量不断扩大,变频器逐渐成为最大谐波源之一。为了解决船舶电力推进电机的谐波问题,将AFE变频器应用于电机控制。本文对推进系统中谐波产生的原因进行分析,并对AFE变频器结构和控制方式进行研究。更多还原

【Abstract】 With the rapid development of electronic technology, nonlinear electronic components are widely used in marine electric propulsion motors, which cause serious harmonic pollution to the power grid. In the ship power system, the inverter capacity continues to expand, gradually become one of the largest harmonic source inverter. In order to solve the harmonic problem of marine electric propulsion motor, AFE converter is applied to motor control. This paper analyzed the causes of harmonic generation in propulsion system, and studied the structure and control method of AFE converter.更多还原
