ABSTRACT:
Methods and apparatus are disclosed for achieving load balance between parallel inverters in an AC power supply. Load balancing reduces undesirable cross conduction current between the parallel inverters. Load balancing and the resulting reduction in cross conduction current are achieved without the need for common control circuitry between the parallel inverters. Thus, the single-fault protection offered by redundant parallel inverters is not compromised by the disclosed load balancing techniques.
