Abstract
A system, including: a plurality of load commutated inverters (LCIs) connected in parallel, wherein each LCI includes: a source bridge for converting an alternating current (AC) voltage to a direct current (DC) voltage, wherein the source bridge includes at least one current switching device; a load bridge for converting the DC voltage from the source bridge to a variable frequency AC voltage; and a DC link coupling the source bridge to the load bridge; wherein each LCI includes a respective current regulator for controlling the at least one current switching device in the source bridge of the LCI to generate a current in the DC link.
