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 PMSG is controlled using a sensorless model reference adaptive system to obtain the rotor position angle. The seven-leg converter is regulated using resonant controllers at the load...
This paper considers the control of a 7-leg back-to-back Voltage Source Inverter (VSI) arrangement feeding a 4-wire load from a 3-phase Permanent Magnet Synchronous Generator (PMSG) operating at variable speed. The 7-leg converter is regulated using Resonant Controllers (RCs) at the load side and self-tuning resonant controllers at the generator side. The control system is augmented by a feed-forward...
The Doubly-Fed Induction Generator (DFIG) is one of the most widely used generators for wind energy applications and more of 50% of the installed Wind Energy Conversion Systems (WECS) are using this sort of variable speed technology. However, the machine requires brushes for the operation which increases the maintenance work. To overcome this drawback a Brushless Double Fed Induction Generator (BDFIG),...
