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...

This paper presents the comparison of Push-Pull Inverter and Z-Source Inverter based Static Compensators (STATCOM).The closed loop system with STATCOM is modeled and simulated using the blocks of MATLAB/SIMULINK.Voltage sag mitigation using Push-Pull Inverter and ZSource Inverter are presented. The present work proposes Z-Source Inverter and Push-Pull Inverter based STATCOM for the control of r...

The current source inverter (CSI) is a power electronics topology that allows for the realization of variable speed drives (VSD). Compared to most common voltage (VSI), which can be directly connected source, CSI needs prestage generate constant bus. This article therefore seeks challenge this “accepted” consideration always precircuit and remove circuit by proposing an innovative i <sub xmlns:...

Non-linear load deteriorates the quality of current waveforms at the point of common coupling of various consumers. Active power filter (APFs) is used to mitigate the most concern harmonic pollution in an electrical network. The controller part is the nucleus of an active power filter configuration. Active power filter performance is affected significantly by the selection of current control te...

This paper is concerned with the design of the power control system for a single-phase voltage source inverter feeding a parallel resonant induction heating load. The control of the inverter output current, meaning the active component of the current through the induction coil when the control frequency is equal or slightly exceeds the resonant frequency, is achieved by a Proportional-IntegralD...

A modified pulse width modulation technique for Z-source inverter based BLDC motor is proposed and analyzed in this project.The Z-source inverter can be used as Buck/Boost converter with lower cost and high efficiency. BLDC motors are used in electric vehicles where portability and efficiency are required. This drive system provides advantages of both BLDC motors and Z-source inverter, and can ...

Abstract— In this paper, an H∞ current controller is proposed to maintain a balanced neutral point for a three-phase fourwire inverter, which can be used in microgrid applications. The neutral-point circuit consists of a conventional neutral leg and a split DC link. The neutral point is balanced with respect to the two DC source terminals (as required, e.g., in neutral-pointclamped three-level ...
