The paper presents a novel secondary reactance control technique in the rotor circuit of a three phase wound rotor induction motor (WRIM). The problem associated with the conventional rotor capacitive reactance control is the demand of exceptionally large capacitance requirement for enhancing the performance of the motor in wide operating range. In the proposed technique, a three phase bridge r...

Now a days wind power energy is playing a major role in power industry. With the raise in application of the wind power variety of topologies are emerging into picture. Within the various types of adjustable speed fixed frequency topologies DFIG is most preferred type because of its efficiency as well as capability to allow wide range of speed variance at simplified converter size. Doubly Fed I...

Because of temperature independence, high resolution and noiseless outputs, brushless resolvers are widely used in high precision control systems. In this paper, at first dynamic performance characteristics of brushless resolver, considering parameters identification are presented. Then a mathematical model based on d-q axis theory is given. This model can be used for studying the dynamic b...
