Abstract
A cascading tap changing regulator has a set of input taps to power both stages of the cascade, each stage having its own series injection transformer to regulate the output. A set of switches are selectively engagable in respective on-off modes to effect a number of regulation steps, and a ratio of the number of steps to the number of switches in the set is greater than 1:1.
