The standard solution for the traction system in battery powered electric vehicles (EVs) is a two-level (2L) inverter feeding a three-phase motor. A simple and effective way to achieve a three-level (3L) inverter in battery-supplied electric vehicles consists of using two standard three-phase 2L inverters with the open-end winding connection of standard three-phase ac motors. The 3L inverter so...

Analysis and practical implementation of the regular symmetric sampled three-phase PWM inverter waveform has been presented in this paper. It is digitally implemented on a Xilinx field programmable gate array FPGA, and the essential considerations involved in the feasibility of using a Xilinx XC4008E software-based to generate PWM has been discussed. All the necessary Xilinx hardware/software t...

This paper deals with the performance analysis of three phase induction motor drive fed by a PWM voltage source inverter. The PWM method, which involves the modulation of conventional sinusoidal reference signal and a triangular carrier is used here to produce pulse width modulated output only for under modulation index. This paper work deals mainly with the performance analysis of three phase ...

This paper presents a hybrid modulation technique consisting of singe-reference six-pulsemodulation (SRSPM) for front-end dc/dc converter and 33% modulation for three-phase inverter. Employing proposed novel SRSPM to control front-end dc/dc converter, high frequency (HF) pulsating dc voltage waveform is produced, which is equivalent to six-pulse output at 6× line frequency (rectified 6-pulse ou...

This paper presents the mathematical modeling of three-phase grid connected inverter fed by Solar Photovoltaic (SPV) system with Maximum Power Point Tracking (MPPT). Analysis has been carried out to choose the proper modulation index for maximum output for three-phase inverter. With this modulation index, the variation of the active and reactive power for different loads has been presented alon...

Three fundamental sine-wave inverter topologies are analyzed: two-leg (one-phase, two-wire); three-leg (three-phase, three-wire); and four-leg (three-phase, four-wire). The topologies are “full-bridge” voltage-source inverters with LC filters suitable for producing sinusoidal output voltages. The switching states and corresponding output voltage vectors produced by each inverter are identified ...

The paper presents a drive system consists of single-phase boost rectifier, space vector pulse width modulation (SVPWM) inverter, and three-phase induction motor. The single-phase boost rectifier is used to obtain near unity power factor and to reduce the harmonic distortion in the main supply. The SVPWM inverter is used to offer 15% increase in the output voltage and low output harmonic distor...

Because of installation for local consumers and since it is free of all contaminations, connecting photovoltaic cells to the grid via single-phase inverter is significantly on the rise. In this paper, a new simple current control is proposed for a single-phase grid-connected voltage source inverter. Using the PQ theory and modelling a single-phase system as an unbalanced three-phase system, a m...
