Abstract

The objective of this paper is to present a design and implementation of space vector pulse width modulation technique to generate the sequence pattern of the PWM inverter driving signals. The aim of the SVM is to optimize the operational characteristics of ac drive by minimizing the harmonics of the currents. The SVM is implemented in the high speed output (HSO) unit of the microcontroller which accepts the outputs of the direct and quadrature current controllers and the flux position angle from the machine model, and gives the three switching pulse patterns required to drive the inverter unit. The essential dead time required for the switching devices is implemented to protect the power switches of the same inverter arm against the short circuit current during the switching transients. In this paper, the space vector modulator and the dead time compensator is configured and implemented completely in a single chip Intel 80C196KC microcontroller in order to minimize the hardware of the system.
