An exemplary embodiment includes a method for balancing thyristor bridge
circuits, the method comprising, determining currents of thyristors in a
first leg of thyristors of a thyristor bridge circuit, determining a
first set of gate firing times for the thyristors in the first leg of
thyristors responsive to determining the current of the thyristors in the
first gate of thyristors, wherein the first set of gate firing times are
operative to balance a current load between the thyristors in the first
leg of thyristors, and gating the thyristors in the first leg of
thyristors according to the first set of gate firing times.
