This paper presents a power factor corrected (PFC) bridgeless (BL) buck–boost converter-fed brushless direct current (BLDC) motor drive as a cost-effective solution for low-power applications. An approach of speed control of the BLDC motor by controlling the dc link voltage of the voltage source inverter (VSI) is used with a single voltage sensor. This facilitates the operation of VSI at fundam...

This paper presents the transient model of a new FACTS device, the center node unified power flow controller(C-UPFC), installed at the midpoint of a transmission line. The C-UPFC consists of three voltage source inverters (VSI) with common DC link. One of the converters is connected in parallel at the midpoint of line and the other two converters are connected in series. The simulation results ...

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>-...

In this study, a fuzzy gain scheduled proportional and integral (FGPI) controller was developed to regulate the power flow regulation of Static Synchronous Series Compensator (SSSC) in a multi-area power system. Also, this FGPI was developed for the SSSC without and with Superconducting Magnetic Energy Storage (SMES) system. Two performance criteria were utulized for the comparison. First, sett...

For high-power electric vehicles (EVs), the drive propulsion based on induction motors is emerging as economical alternative. Compared to conventional motors, open-end winding motor (OEWIM) requires only half dc-bus voltage for given torque. The EV power train dual two-level voltage-source inverter (VSI)-fed OEWIM with isolated dc sources used in this research. uniform state-of-charge (SoC) dis...

In this article, a new solar PV fed Dynamic Voltage Restorer (DVR) based on Trans-Z-source Inverter (TransZSI) is proposed to improve the power quality of on-grid Photovoltaic (PV) systems. DVR electronic compensator using for injecting desired voltage Point Common Coupling (PCC) as per disturbance. DVR, in place traditional VSI, TransZSI with outstanding merits buck/boost, broader range boost ...

In this paper, a three-phase drive with a six-leg Voltage Source Inverter (VSI) and an open-end winding Interior Permanent Magnet Synchronous Machine (IPMSM) designed for the traction of an electric vehicle is studied in flux-weakening operation. The topology allows the functionality of a high power charger to be obtained, without adding any other supplementary power devices. On the other hand,...
