Development of a Brushless AC Servo Drive for the Tube Locator Module for Steam Generator Tube Inspection Device

The fundamental issue in the area of remote handling and robotics is the reliability of power electronics system. Detailed analysis and simulation studies are very much relevant as the prebuilt drive solutions are costly and performance of drive system depends upon the reliability of control algorithms incorporated in the drive. The modulation techniques also play an important role in the dc voltage utilization. This paper presents a comparative simulation study for the analysis of complete BLAC drive using PI controller using two types of modulation techniques namely Sinusoidal Pulse Width (SPWM) and Space Vector Modulation (SVPWM).
