Abstract: A power converter includes an output converter having a 3-phase or higher output, an inductor coupled to the output converter and a switch device coupled to the inductor. The switch device charges the inductor via a DC input during a first stage of a switching cycle of the switch device. The output converter discharges the inductor to a load coupled to the 3-phase or higher output during a second stage of the switching cycle. The output converter includes a phase leg for each phase of the 3-phase or higher output, each phase leg having a first thyristor device connected in series with a second thyristor device. Each phase of the 3-phase or higher output originates between the first thyristor device and the second thyristor device of the corresponding phase leg.
