Tīmeklis2024. gada 2. apr. · The SV-PWM block generates PWM signals based on the Space Vector Modulation (SVM) algorithm. This algorithm determines the three vectors that are the closest to the reference vector and computes the dwell times for each one. Based on those times, a duty cycle is computed and a triangular carrier is used to generate the … Tīmeklis至此,svpwm的工作完成了,我们得到了每一时刻所需要的空间电压矢量以及它们持续的时间,在处理器中赋值给对应通道的捕获比较寄存器产生相应的三个pwm波形,控制mos管的开关,进而产生我们期望的电压、电流、力矩。
