ABSTRACT:
A power control or conversion apparatus comprises a combination of a controlled electric valve bridge and an electric valve bridge being coupled to each other in anti-parallel combination; DC reactors inserted in series in positive and negative electric paths coupling the controlled electric valve bridge with the electric valve bridge in anti-parallel combination; extension means for reverse-biasing the controlled electric valves of the controlled electric valve bridge to extinguish them; and switching means inserted in the coupling portion between the respective electric valve bridges and a DC power source. The extinction means and the DC reactors cooperate to forcibly commutate the controlled electric valve. The DC reactors also make current smooth.
