Medium voltage ac machines driven by high-power inverters operate at reduced switching frequency in order to restrain the switching losses of the power semiconductor switches. When synchronous optimal pulsewidth modulation is employed, the harmonic distortion of the machine currents is minimized under steady-state conditions. High-performance drives may be subjected to sudden changes of velocity and load. Conventional current-based closed loop control schemes cannot ensure dynamic operation… CONTINUE READING
