SPEED CONTROL OF SYNCHRONOUS MOTOR BY USING VARIABLE FREQUENCY DRIVES ABSTRACT : A novel open-loop speed control method for induction motors that provides high output torque and nearly zero steady-state speed error at any frequency is presented. The control scheme is based on the popular constant volts per hertz (V/f) method using low-cost open-loop current sensors. Only stator current measurements are needed to compensate for both stator resista ....etc [:=Read Full Message Here=:]

Title: Z-Source Inverter for Motor Drives Page Link: Z-Source Inverter for Motor Drives - Posted By: smart paper boy Created at: Wednesday 22nd of June 2011 06:12:05 PM	z source inverter ppt slides, ac motor drives free pdf gujarati, dc motor drives seminar paper, ppt presentation of z source inverter, current source inverter, automatic source inverter pdf, projects using z source inverter,
Abstract This paper presents a Z-source inverter system and control for general-purpose motor drives. The Z-source inverter system employs a unique LC network in the dc page link and a small capacitor on the ac side of the diode front end. By controlling the shoot-through duty cycle, the Z-source can produce any desired output ac voltage, even greater than the line voltage. As a result, the new Z-source inverter system provides ride-through capability duringvoltage sags, reduces line harmonics, improves power factor and reliability, an ....etc [:=Read Full Message Here=:]

FLUX ESTIMATORS FOR SPEED-SENSORLESS INDUCTION MOTOR DRIVES Abstract This thesis deals with flux estimators for speed-sensorless induction motor drives. To enhance the stability and the performance of state-of-the-art sensorless drives, new flux estimator designs based on the standard motor model are proposed. Theoretical and experimental research methods are both used. The dynamics and stability of flux estimators are analyzed using linearized models, and the effects of parameter errors are investig ....etc [:=Read Full Message Here=:]

IMPEDENCE - SOURCE INVERTER FOR MOTOR DRIVES Traditional Source Inverters Voltage Source Inverter. Current Source Inverter. Voltage Source Inverter Problems This inverter can be used only for Buck operation. For application where the required output voltage is high, an additional dc-dc boost converter is needed to obtain a desired ac output. This inverter does not have ability to provide ride-through during voltage sags . additional power converter stage increases system cost and lowers efficiency. ....etc [:=Read Full Message Here=:]
