Inverting mode failure recovery: application to the drive of a DC generator supplied by a three-phase thyristor converter

In this paper, we present a new control strategy for industrial applications with static converters. It is based on a reconfiguration of the firing sequence and on a resetting of a digital controller. Applied to the nonautonomous inverting mode it allows guarantee of a maximal efficiency without decreasing the dependability of the electromechanical process.
