| Abstract |
An Extinction Angle Controller (EAC) reduces the flow of lagging VAR in a Dual Convertor Drive by forced commutation of the rectifier convertor. A state space model of an experimental drive is validated through a comparison of the results of digital simulation with the experimental results. The simulation makes use of a logic module for determining the successive modes of operation of the system and predicts the 'Main ' as well as 'Transition' modes introduced by the EAC. Digital simulation also yields substantial information about the performance of the drive in respect of line power factor, displacement factor, harmonic content in the input current and other parameters of interest to the system designer like power dissipation in the diodes and thyristors in the main circuits as well as in the auxiliary EAC module. |
