Permanent Magnet Synchronous Motor Drive Based on Modified Space Vector Pulse Width Modulation

Abstract

The paper introduces a modified space vector pulse width modulation strategy which has been used to drive and control the speed of permanent magnet synchronous motor. This strategy, compared with relative conventional SVPWM method, has important features. Such features are increasing the utilization of DC link input voltage of the inverter, reducing the stress on power switching devices, and therefore minimizing the switching losses. The proposed approach is analyzed and simulated. Also a complete system model of the permanent magnet synchronous motor (PMSM) drive, using MatLab-Simulink, has been performed. The obtained results, for conventional and modified approaches, have been compared. In order to verify the theoretical results, practical test has been performed which shows that the proposed technique is preferable than the conventional type.

Parameters Variation to Estimate Performance Characteristics of 3-Phase Asynchronous Motor

“…Actually, in an electrical machine simulation which acts as a very important technique needed more other fields. The schematic block of a complete SCIM dynamic model indicates all programmable inputs voltage source of 3-phase ideal power supply to the machine with a cylinder rotor type results in no reluctance torque between rotor and stator field (Saied & Mohammed, 2016) with specific parameters and output of Hydro-Mechanical pump as a dynamic load controlled by mechanical valve based on suitable step functions. MATLAB simulation codes transfer deferential functions into a mathematical system to produce efficient items and static calculations using sensors based on a real-time variation of speed, efficiency, torque, and machine active power in perunit multi-degree dimensions.…”
