摘要：
A power converter utilizes first and second thyristor bridges energized by two AC power sources which are insulated from each other. The power converter includes first and second auxiliary thyristor circuits each containing plural thyristors, and a commutation circuit. The cathode of each thyristor of first auxiliary thyristor circuit is connected to one of the AC power sources, and the anode of respective thyristors are connected each other at a common node. The anode of each thyristor of second auxiliary thyristor circuit is connected to the other of the AC power sources, and the cathode of respective thyristors are connected each other at another common node. The commutation circuit is connected between the common nodes of the first and second auxiliary thyristor circuits.
