This paper presents the modeling, rapid control prototyping, and hardware-in-the-loop testing for real-time simulation and control of a grid-connected doubly fed induction generator (DFIG) in a laboratory-size wind turbine emulator for wind energy conversion systems. The generator is modeled using the direct-quadrature rotating reference frame circuit along with the aligned stator flux, and the...

The brushless DC motor used in ISAD of Electric and Hybrid Electric Vehicles is introduced in this paper. Magnet field distribution and static characteristic of permanent magnet brushless DC motor are calculated by finite element methods.

The objective of the present study was to deal with the rotordynamics of the rotor of an ultra-high speed PM type synchronous motor-generator for a 500 W rated micro gas turbine generator. This paper introduces dynamic analysis, and experiments on the motor-generator. The focus is placed on an analytical approach considering the mechanical dynamic problems. It is essential to deal with dynamic ...

Brushless dc (BLDC) motor drives are continually gaining popularity in motion control applications. Therefore, it is necessary to have a low cost, but effective BLDC motor speed/torque regulator. They are used in Residential and commercial appliances such as refrigerators and air conditioning systems with conventional motor drive technology. A Brushless DC (BLDC) drives are known for higher eff...

In this paper we present an approach to the conversion of the power generated by a seawave power generator integrated in an offshore wind power farm. The article is focused on low power generators that could be used in offshore installations. The generator is a Permanent Magnet (PM) linear generator that generates highly distorted emfs. We propose and compare two possible ways to connect the ge...

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 ...

This paper addresses the problem of controlling wind energy conversion systems (WECS) which involve permanent magnet synchronous generator (PMSG) fed by IGBT-based buck-to-buck rectifier-inverter. The goal of the control is to maximize wind energy extraction and this necessitates letting the wind turbine rotor operate in variable-speed mode. The control strategy involves: (i) a nonlinear regula...
