An ice machine adapted into an autonomous photovoltaic system without batteries using a variable-speed drive
(JOHN WILEY & SONS LTD, 2010)
The adaptation of a commercially available ice machine for autonomous photovoltaic operation without batteries is presented. In this adaptation a 1040 W(p) photovoltaic array directly feeds a variable-speed drive and a 24 ...
Energy harvesting from the vibrations of a passing train: Effect of speed variability
(2016-10-03)
This paper builds on a previous study which investigated the amount of energy that could be harvested from the vibration induced by a passing train using a trackside energy harvester. In that study, the optimum parameters ...
Speed estimation for induction motor using neural networks method
(2013-07-15)
This work presents an alternative approach based on neural network method in order to estimate speed of induction motors, using the measurement of primary variables such as voltage and current. Induction motors are very ...
An Enhanced dq-Based Vector Control System for Modular Multilevel Converters Feeding Variable-Speed Drives
(IEEE, 2017)
Modular multilevel converters (M2C) are considered an attractive solution for high power drive applications. However, energy balancing within the converter is complex to achieve, particularly when the machine is operating ...
Self-Tuning Resonant Control of a Seven-Leg Back-to-Back Converter for Interfacing Variable-Speed Generators to Four-Wire Loads
(IEEE, 2015)
This paper considers the control of a seven-leg back-to-back voltage source inverter arrangement, feeding a four-wire load from a three-phase permanent-magnet synchronous generator (PMSG) operating at variable speed. The ...
Quality of mechanical soybean harvesting at two travel speeds
(2017-01-01)
Soybean harvesting is the last operation performed in the field and therefore has high added value. Quantitative losses during this process should therefore be minimized to achieve maximum quality and increase the ...
QUALITY OF MECHANICAL SOYBEAN HARVESTING AT TWO TRAVEL SPEEDS
(Soc Brasil Engenharia Agricola, 2017-11-01)
Soybean harvesting is the last operation performed in the field and therefore has high added value. Quantitative losses during this process should therefore be minimized to achieve maximum quality and increase the ...
High Speed Milling Of Hardened Steel Convex Surface
