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 ...
Smart Algorithms to Control a Variable Speed Wind Turbine
In this paper, a robust adaptive fuzzy neural network sliding mode (AFNNSM) control design is proposed to maximize the captured energy for a variable speed wind turbine and to minimize the efforts of the drive shaft. Fuzzy ...
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 ...
