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...

Various sigma–delta ( $\Sigma$ notation="LaTeX">$\Delta$ ) modulation techniques for reducing the maximum peak-to-peak amplitude of common-mode voltage (CMV) by 80% in a five-phase, high-frequency source inve...

Abstract Although increasing the number of switches increases switch losses, most designed controllers focus on controlling an inverter circuit with more than six switches. The paper aims to address this issue that arises in implementation voltage source (VSI) for brushless DC (BLDC) motors. It optimises sinusoidal pulse width modulation (PWM) controller, minimising total harmonic distortion (T...

The operation of a voltage source inverter (VSI) depends on its output LC filter and the PWM modulator delay. VSI model includes serial equivalent resistance based resistances active bridge transistors, coil winding, additional PCB elements, such as traces connectors, in addition to large that result from power losses core switches. These dynamic depend switching frequency load. This paper inve...

Voltage source inverter (VSI) had been used in dc traction power substation to deliver the trains braking energy back utility grid. To mitigate low order harmonics components, pulse-width-modulation (PWM) technique is commonly VSI controlled. As a result, ac voltage and current waveforms may contain high frequency ripples. This paper proposes using LCL-filter with series <em>R</em>-...
