摘　　要：对于三相电压型DC/AC逆变器,在对空间电压矢量脉宽调制(SVPWM)分析的基础上,利用空间矢量的对称性提出了一种较传统SVPWM算法计算量明显减少且易于程序实现的新算法,并将其应用到带三相负载的系统,对该系统进行了仿真分析,结果表明所提出算法有效且实用。Based on the analysis of SVPWM theory for three-phase DC/sdAC voltage inverter, using the symmetry of space vector, a novel algorithm is proposed in this paper. This novel algorithm reduces computation burden and is easy to realize in program comparing to the traditional method. Results of simulation show it is valid.
