摘　　要：SVPWM控制策略的直流电压利用率高、动态响应快,可应用于船舶轴带发电机的逆变电路系统控制中。结合Z源逆变器的电路结构、工作状态及工作原理,在matlab/simulink中搭建Z源逆变器作用下的船舶轴带发电机SVPWM仿真控制系统。通过仿真可知,系统不仅可输出满足条件的并网电流和电压,且可通过调整直通零矢量占空比获取不同的线电压。The space vector pulse width modulation （SVPWM） has the advantages of high utilization of DC voltage and fast dynamic response, so it is used in the inverter circuit control system of the marine shaft generator system. Combining with the cir- cuit structures and working states of the Z-source inverter,the operation principle of SVPWM is discussed in details in this study. The simulation model of the marine shaft generator system is built in matlab/simulink. From the simulation waveforms, the output- ring grid voltage and grid current can satisfy the working requirements, and the different line voltages can be obtained by adjusting the duty ratio of short-through zero-vector.
