摘　　要：针对船用变频电源电能质量问题,提出了一种三电平空间矢量控制策略。在介绍了船用变频电源的原理及意义的基础之上,选择电源的拓扑结构为交-直-交型。分析了三电平空间矢量控制策略后,在Maltab/Simulink下对船用变频电源及三电平空间矢量控制策略进行建模和仿真,结果表明该控制策略能实现电源幅值和相位的变化,变频效果好;三电平空间矢量控制有效地提高了电源的输出电能质量。Aiming at the problems of power quality in inverter-based power supplies, a three electrical level SVPWM control strategy was proposed. On the basis of introducing the principle and significance of inverter-based power supplies, the AC-DC-AC topology was chosen. After analyzing briefly the three electrical level SVPWM control strategy, model and simulate the whole system under Maltab/Simulink, and the results indicate that the proposed control strategy can achieve the changing of amplitude and phase, and the effect of inverter is good. At the same time, three electrical level SVPWM could enhance the power quality effectively.
