摘要: For the period where an Op vector and a b are outputted continuously among periods output voltage vectors of each phase in PWM period, time is divided by positive integer m to determine division vector, alternately repeatedly times for times. On (a) continuously, n times, thus spreading frequency components current ripple resulting from pulses (1)-(3).
