Abstract

Abstract : In the field of power electronics Pulse Width Modulation (PWM) inverters play a major role for DC to AC conversion. Space Vector Modulated PWM (SVPWM) is the popular PWM method and possibly the best among all the PWM techniques as it generates higher voltages with low THD and works very well with field oriented (vector control) schemes for motor control. Good quality output spectra can be obtained by eliminating several low order harmonics by adopting a suitable harmonic elimination. In this paper, the modeling, implementation and simulation of Hysteresis controlled SVPWM are defined. There is also a sort of technique defined for getting better response of space vector via a hysteresis filter, and to control of generating specific error free vectors from switching. Simulation results give the hope to further development of space vector technique in many control systems especially in this case an inverter.
