用了传统的SVPWM方法，大扇区根据角度来判断的，小扇区是根据Vbeta与Valpha、udc的几何关系来判断，通过将其他扇区转化为第一个大扇区来仿真，得到了结果-With the traditional SVPWM method, based on large-sector perspective to judge, based on a small sector Vbeta and Valpha, udc geometry judged by the other sectors into the first major sector to computer simulation, result
