ABSTRACT:
A current director and interface circuit to prevent damage to a transformer relay by the simultaneous activation of a plurality of bidirectional switches. A current director prevents current flow in the secondary winding of the transformer relay in a second direction above a predetermined switching threshold for a predetermined succeeding time period after current has flowed in the secondary winding of the transformer relay in a first direction above a predetermined inhibit threshold during a predetermined preceding time period.
