The global regulator CodY controls the expression of dozens of metabolism and virulence genes in the opportunistic pathogen Staphylococcus aureus in response to the availability of isoleucine, leucine and valine (ILV), and GTP. Using RNA-Seq transcriptional profiling and partial activity variants, we reveal that S. aureus CodY activity grades metabolic and(More)
This paper presents the design optimization of linear induction motor. Application of linear induction motor includes various industrial processes like conveyor belt, vertical movement, steel power plant, induction heating and automated material handling. All these applications require an efficient and high torque providing linear induction motor. Objective(More)
In this paper, two three-phase three-level Neutral Point Clamped (NPC) converters connected back-to-back are used for a direct drive wind power generator. A permanent magnet synchronous generator (PMSG) is used as the generator, which is driven by the wind turbine. Main problem of voltage unbalance in each electrolyte capacitor is controlled by using a(More)
In this paper, a three-level inverter fed induction motor drive operating under Direct Torque Control (DTC) is presented. DTC do not show good performance in low speed region due to stator flux demagnetization that relates to variation in stator resistance. Here, a sinusoidal wave is used as dither signal of minute amplitude (for torque hysteresis band and(More)
Usually Photovoltaic panel depends on two major parameters temperature(T) and irradiance(G). Many researchers have studied the effect of these two parameters on the performance of photovoltaic panel. Parasitic resistance of the PV panel has major impact on its performance which is often overlooked. Therefore, in this paper we have analysed the effect of(More)
In this paper, the dynamic performance of a grid connected photovoltaic (PV) power system of a distribution networks is studied and experimental results are presented. Due to oscillating nature of the PV power plant, the grid integration requires stable and steady power injection with good power quality (PQ). Hence, the PQ analysis has been carried out(More)
Industrial and traction drives (used in automobile and electric locomotives) using induction motor, require a good control over torque and speed, reversible and regenerative speed control operation. Hence the drive topology requires both ac to dc conversion and dc to ac conversion system. In this paper, a three-level utility friendly the front-end neutral(More)
In this paper, the modeling and control of the DC sub-grid, fed from Solar panels and integrated into the grid using dual active bridge (DAB) converters, is studied. The dynamic performance of the DAB converter depends on accurate modeling of the system. A small signal (SS) modeling of DAB converter is developed for the closed loop control and its dynamics(More)
This paper presents the systematic design methodology for the design of electric vehicle propulsion system. Power rating of three phase induction motor is calculated to achieve the pre-specified vehicle dynamic characteristics. The effect on electric motor power rating with variation of vehicle maximum speed is analyzed. Simulation results for vehicle(More)
