چکیده
In recent years, electric propulsion systems have become widely, used and these strict limits in volume weight. Therefore, it is necessary to reduce the weight of inverter-motor drive system. a typical system, at least phase current sensors are required. order number sensors, this paper proposes method for measuring using DC link Two currents per system measured during one period switching frequency pulse width modulation (PWM) shift method. However, since contains an error component average current, was compensated obtain similar actual by slope dwell time current. The effectiveness proposed verified through experiments.

Reconstruction of Phase Current of Induction Motor Drive based on DC Link Measurement
The aim of this paper is the study of speed sensorless control of IM drive by using dc link quantities. The sensorless control method is to determined the appropriate moment when the motor winding should be commutated. This moment is determined by the rotor position. In this type of drive, the limitations of using various sensors for the measurement of rotor speed, stator current & voltages are...

The proposed sensor less method cl...
متن کاملRobust method for stator current reconstruction from DC link in a sensorless induction motor drive
The electronic inverters normally operate in a current controlled mode. Current controllers are prone to errors associated with nonlinearity and offsets in the current transducers. Their successful operation requires measurement of the instantaneous values of stator currents. Using the switching signals and dc link current, this paper presents a new algorithm for the reconstruction of stator cu...
متن کاملSensorless induction motor drive with a single DC-link current sensor and instantaneous active and reactive power feedback
This paper proposes a novel torque and speed control structure for low-cost induction motor variable-speed drives with a single dc-link current sensor. The controller is based on reconstruction of the active and instantaneous reactive power from the dc-link current without the use of a shaft sensor. An effective way of achieving tracking of set values of motor torque and flux is to base the est...
