TL;DR: In this article, a power converter for power conversion between an a.c. system and a d.c system includes a full-wave bridge circuit having GTO connected in at least one arm of the full wave bridge circuit on the positive polarity side during a conduction-enabled period of GTO which is determined by a firing phase angle, the GTO is so controlled as to perform current chopping operation by a pulse signal of a predetermined pulse width.
