Abstract
A DC to DC power converter of the chopper-type includes a reverse conducting main thyristor device, or equivalent, and a saturable autotransformer in the power path of the main thyristor device, the autotransformer being in the saturated state when the main thyristor device is conducting, and a gated capacitor commutating circuit to desaturate the autotransformer for commutating the main thyristor device out of conduction.
