This paper presents a scalar volt per hertz (v/f) control technique for maximum power tracking of a grid-connected wind-driven Brushless Doubly-Fed Reluctance Generator (BDFRG). The proposed generator has two stator windings namely; power winding, directly connected to the grid, and control winding, connected to the grid through a bi-directional converter. The presented control technique is based...
This paper presents two six-phase open-end machine conversion systems. They are composed of three three-leg converters connected in series to a six-phase machine with open terminals, in an open-end winding connection. The converters use diodes to replace controlled switches, making the conversion system non-reversible and with a reduced number of controlled components. In this case, the machine must...
This paper reports on the control necessary in a Bristol cylinder sea-wave energy capture device and the issues concerned with harvesting a slow, propagating sea-wave, where the power will pulsate. In the paper a detailed description is put forward for the mechanical system. The control strategies necessary to control a system that is has continuously changing conditions are outlined and simulations...
