Three-phase filtered SVPWM motor drive

2016 5th International Symposium on Next-Generation Electronics (ISNE), 2016
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 ...
