In the digital implementation, PWM pulses can only change switching states at some specific time instants depending on the system clock frequency. This phenomenon results in the deviation between the desired and the produced phase voltages. Although the deviation is small in each carrier period, the accumulated error will result in large current harmonics for inductive load. In this paper, a high-order filtered SVPWM is proposed for the three-phase motor drive to overcome this problem. By further incorporating the band-stop filter, the specific harmonic component is reduced. Two experiments confirm the reliability and applicability of the proposed modulator.
