Abstract :
This paper proposes techniques to exploit the capability of modern power converters to operate at high switching frequencies. This is done for two reasons: (1) to improve the quality of the pulse width synthesized waveforms supplied by a voltage source inverter to an alternating current machine within a microcomputer-based machine drive system; and (2) to compensate for the dead time due to the data acquisition and control algorithm computation
