A simple neuro-controlle r for a synchronous generator is presented in this paper. The controller performs the function of the terminal voltage control. By representing the proposed neuro-controller in s-domain, its parameters to ensure system stability can be obtained analytically. Results of simulation studies on a non-linear seventh order generator model with the neuro-controller using calcu...

The unbalanced voltages cause negative effects on the doubly fed induction generator (DFIG) such as torque pulsation and increased stator current. Based on the symmetrical component theory, the torque pulsation is the consequence of the interaction of stator and rotor currents of different sequences. This paper presents a control technique to reduce the effect of unbalanced voltages on the DFIG...

This paper presents an interleaved resonant converter to reduce the voltage stress of power MOSFETs and achieve high circuit efficiency. Two half-bridge converters are connected in series at high voltage side to limit MOSFETs at Vin/2 voltage stress. Flying capacitor is used between two series half-bridge converters to balance two input capacitor voltages in each switching cycle. Variable switc...

The fly back converter has been widely used for multi outputs due to the simple structure and low cost in low-power applications. This paper presents a new multi output converter. It consists of a half-bridge inverter with boost converter in primary side and a fly back rectifier that is integrated with an auxiliary buck converter in secondary side. The boost converter is used to generate high v...

As an integral part of the Smart Grid, smart transformers both work independently to constantly regulate voltage and maintain contact with the smart grid in order to allow remote administration if needed and to provide information and feedback about the power supply and the transformers themselves. Through a process known as voltage optimization, a smart transformer provides the exact amount of...

In the modern world, electric drive has tasks of different nature, depending on application and technological process. At moment, induction drives, which operate by direct start, are widely used. This method negative factors: high starting currents at launch; impact loads mechanical system. During continuous running mode motor with its resource system is reduced. Thyristor voltage regulators us...
