Analysis and FPGA Realization of a Pulse Width Modulator Based on Voltage Space Vectors
Pulse width modulation based on space vectors (SVPWM) technique has become the most popular and important PWM techniques for three phase voltage source inverters (VSI). In this paper, we present the analysis and realization of SVPWM for variable speed control of AC motor drives, employing Xilinx Spartan 3E FPGA device. The selection of zero vectors and space vector sequence are given and the po...

متن کاملPulse Width Modulator for Voltage Regulation in Voltage Source Inverter
Pulse Width Modulated (PWM) voltage source inverters (VSIs) are extensively used in industrial and domestic applications. The versatile natural sampled sinusoidal PWM (SPWM) method can perform output voltage control with acceptable indices. In these PWM-VSI, the coarse voltage regulation is done with change in modulation depth while fine voltage regulations have not been addressed by other auth...

متن کاملA Vector Controlled Induction Motor Drive with Neural Network Based Space Vector Pulse Width Modulator
A neural network based implementation of space vector modulation of a voltage-sourced inverter has been proposed in this paper. Use of ANN based technique avoids the direct computation of trigonometric function (e. g. sine function) as in conventional space vector modulation implementation. The main disadvantages with conventional implementation are, use of any look-up table implies the need fo...
