A Novel VSI and CSI Fed Active-Reactive Induction Motor Drive with Sinusoidal Voltages and Currents

Abstract Till date Load Commutated Inverter (LCI) fed synchronous motor drive configuration is popular in high power
applications(>10 MW). The leading power factor operation of synchronous motor by excitation control offers this simple and rugged
drive structure. On the contrary, LCI fed induction motor drive is absent as it always draws lagging power factor current. Therefore
complicated commutatio ....etc

reactive and non reactive suspension system

Suspension is the system of tires, tire air, springs, shock absorbers and linkages that connects a vehicle to its wheels and allows relative motion between the two. Suspension systems serve a dual purpose contributing to the vehicle's roadholding/handling and braking for good active safety and driving pleasure, and keeping vehicle occupants comfortable and a ride quality reasonably well isolated from road noise, bumps, vibrations,etc.These goals are generally at odds, so the tuning of suspensions in ....etc

ENHANCED PERFORMANCE OF A DOUBLY FED
WIND-POWER INDUCTION GENERATOR AT WIND-
RANGE BOUNDARIES
ABSTRACT
The doubly fed induction generator (DFIG) is one of the largest generators used
with MW-class wind turbines. This paper focuses on the weak performance areas
of grid-connected DFIG-based wind turbines. Basically, the DFIG performance at
low wind speeds, close to the cut in speed, and around the full rating operation (in
the vicinity of rated wind speed) is investigated. For low wind speed region, the
causes of decreased efficiency ....etc
