Abstract
In a static VAR generator for providing reactive power compensation to an ac network and including a thyristor-switched capacitor bank having the series combination of a capacitor, a bidirectional thyristor switch having gate drive, and a current limiting inductor with an applied voltage appearing across the combination with a current being conducted therethrough, a damping circuit and method for switching the thyristor switch to achieve damping of oscillatory transients generated by the switching of the capacitor in the network, comprising:
