This paper presents a simple generalized pulse width modulation (GPWM) algorithm for direct torque controlled induction motor drives. Though the classical direct torque control (DTC) algorithm gives fast dynamic response, it gives large steady state ripples and variable switching frequency operation of the inverter. To overcome these problems, space vector pulse width modulation (SVPWM) algorit...

This paper presents a new circuit realization on single on chip for the space-vector pulse-width modulation (SVPWM) strategy. An SVPWM control integrated circuit (IC) has been developed using the state-of-the-art field-programmable gate array (FPGA) technology. The proposed SVPWM control scheme can be realized using only a single FPGA (XC4010) from Xilinx, Inc. presents the design and Implement...

The fundamental principle of SVPWM is introduced in this study. The design on the structure of threephase voltage type PWM rectifier system based on SVPWM control was also discussed. Then we calculate the DC capacitor and AC side inductance. The computer simulation tool MATLAB/Simulink is taken and the result is shown in the end. The result indicates that the design of such platform is feasible.

This paper compares and evaluates the performance of Sinusoidal Pulse Width Modulation (SPWM) and Space Vector Pulse Width Modulation (SVPWM) techniques for a three-level inverter by cascading two two-level inverters. In this topology, four power semiconductor switches are used per phase and a total of twelve switches are required. The simulation study shows that SVPWM is superior to SPWM in th...

This paper deals with the efficiency optimization of Field Oriented Control (FOC) of a six–phase induction motor supplied by Space Vector PWM (SVPWM) using the flux Search Controller (SC) technique. The proposed technique is based on controlling flux to achieve maximum efficiency at light load or low speed. Flux search controller technique is not only cost effective and easy to implement but al...

Induction machine drive based on Direct Torque Control (DTC) allows high dynamic performance with very simple hysteresis control scheme. Conventional Direct Torque Control (CDTC) suffers from some drawbacks such as high torque ripple and variable switching frequency , difficulties in torque as well as flux control at very low speed. This paper is aimed to analyze DTC principles, the strategies ...

Abstract: A method is proposed for reducing speed ripple of permanent magnet synchronous motors (PMSMs) controlled by space vector pulse width modulation (SVPWM). A flux graph and mathematics are used to analyze the speed ripple characteristics of the PMSM. Analysis indicates that the 6P (P refers to pole pairs of the PMSM) time harmonic of rotor mechanical speed is the main harmonic component ...
