Instantaneous voltage measurement technique for PWM voltage source inverters
International Journal of Power Electronics, 2008The pulse width modulated (PWM) voltage source inverter (VSI) is almost universally used in industrial motor drives. Although measurement of the VSI output voltage is required in many applications, accurate measurement is problematic due to the high frequency inverter switching.

Analysis of Voltage Source Boost Inverter
2018Voltage source boost inverter is different from voltage source inverter owing to the fact that former provides higher ac output voltage with respect to dc input voltage as compared to the latter. The single-phase voltage source boost inverter is a single stage power conversion device that produces higher value of ac output voltage with the application ...

Instantaneous Phase Voltage Sensing in PWM Voltage-Source Inverters
IEEE Transactions on Power Electronics, 2018The output voltage of power electronic converters is a very important quantity for dynamic control of power electronic systems. In electrical drives without electromechanical position or speed sensor, the terminal reference voltage is used to obtain the rotor position.

Grid connected voltage source inverter control during voltage dips
2009 35th Annual Conference of IEEE Industrial Electronics, 2009This paper proposes a combined synchronization method for full scale converter of wind turbine (WT) aiming to ride trough balanced and unbalanced voltage dips due grid faults. A Kalman filter synchronization (KFS), capable extract the positive and negative sequence grid voltages, is designed to have a fast response to voltage disturbances.

Effect of supply-voltage unbalance on voltage-source inverter
3rd IET International Conference on Power Electronics, Machines and Drives (PEMD 2006), 2006Properties of the control method for the compensation of unbalanced voltage supply that eliminates pulsating current in the DC bus of a voltage source inverter are analyzed. These pulsations can have negative effects on operating properties of the drive as well as on the quality of power supply in the electrical vicinity of the inverter.

Voltage source inverter: four-quadrant operation
2009This section describes two ways in which this form of a.c. motor drive can decelerate a motor and its load with a simple rectifier input stage. Also described is an alternative active rectifier stage that can be used in conjunction with a voltage-source inverter to facilitate full four-quadrant operation.
