Algorithms of Space Vector PWM in Overmodulation Area

Abstract

The aim of this paper is the comparison and evaluation of different space vector PWM (SVPWM) strategies enabling the continuous transition from the linear modulation to the six-step mode. One of the important factors to be explored is the frequency analysis of the motor quantities in order to be able to evaluate the possible impact of the drive on the traction mains – specifically the impact on the railway signaling
