Modulation of Current Source Inverter [PDF]

open access: yesJournal of Intelligent Procedures in Electrical Technology, 2011
Direct torque control with Current Source Inverter (CSI) instead of voltage source inverter is so appropriate because of determining the torque of induction motor with machine current and air gap flux. In addition, Space-Vector Modulation (SVM) is a more

Hysteresis current control of a vector controlled induction motor and DTC: an assessment

open access: yesInternational Journal of Electronics, 2004
This paper presents the speed control of an induction motor using nonlinear current control in rotating coordinates. Two hysteresis comparators and the position of the motor flux are used to generate directly the gate pulses for the power transistors of the inverter.

How effective is integrated vector management against malaria and lymphatic filariasis where the diseases are transmitted by the same vector? [PDF]

open access: yes, 2014
The opportunity to integrate vector management across multiple vector-borne diseases is particularly plausible for malaria and lymphatic filariasis (LF) control where both diseases are transmitted by the same vector.
