Abstract:
A hybrid on-load tap changer, for use in high voltage alternating current power transmission, including a selector and a diverter having two legs defining respective current paths. Each leg includes a pair of opposed first and second semiconductor switches. The hybrid on-load tap changer also includes a controller configured to switch on one of the first or second semiconductor switches of a given leg at a predetermined point within the alternating current cycle so as to commutate off a desired semiconductor switch in the other leg.
