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 ...
Six-element circuit for maximum power point tracking in photovoltaic-motor systems with variable-frequency drives
(JOHN WILEY & SONS LTD, 2010)
A low-cost circuit was developed for stable and efficient maximum power point (MPP) tracking in autonomous photo voltaic-motor systems with variable-frequency drives (VFDs). The circuit is made of two resistors, two ...
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 ...
A Novel Control System for Medium-Voltage Hexverter-Based Drives
(2020-09-23)
In this paper, a novel control system for the
Hexverter-based drive is proposed and analysed. Unlike
previously proposed control schemes, the proposed one
does not require the information of the machine variables
to ...
