The paper presents the modeling, simulation and analysis of an AC-DC converter based PWM rectifier. It provides a suitable control algorithm for a pulse width modulation rectifier which reduces ripple from the DC output side as well as shapes the input current properly. The basic objective of a PWM rectifier is to regulate the DC output voltage and also ensure a sinusoidal input current and unity power factor operation. This is implemented by high speed IGBT switches connected in anti parallel mode across the rectifier diodes
This paper proposes a coordinated control of rotor side converters (RSCs) and grid side converters (GSCs) of variable speed doubly-fed induction generator (DFIG) based wind generation systems under unbalanced voltage conditions. The control scheme uses stator flux-oriented control for the rotor side converter and grid voltage vector control for the grid side converter. System behaviours and operations of the RSC and GSC under unbalanced voltage are illustrated. The cocoordinated control schemes manage to restore the wind turbines normal operation after the clearance of fault
This paper presents a novel low-cost, highly efficient, reliable and compact motor drive topology for residential and commercial application. The Brushless DC (BLDC) motor is a simple robust machine which has found application over a wide power and speed of ranges in different shapes and geometry. This paper briefly reviews the fundamentals behind the motor and also the different types of BLDC motors with different geometries and then presents a new configuration for BLDC motor/generator, which does not use a permanent magnet in the rotor. A new soft-switching boost converter is proposed in this paper. The conventional boost converter generates switching losses at turn ON and OFF,
