Patent ID: 7277304

Claim:
A multiple DC-to-AC inverter system, the inverter system comprising: a plurality of inverters, each having a DC input and an AC output, and each being configured to generate, at its AC output, a respective AC output signal in response to a DC input signal applied to said DC input; a plurality of gate drives, each having a gate drive input and a gate drive output coupled to a respective one of said inverters, and each being configured to produce, at its gate drive output, an inverter drive signal set in response to a gate drive signal set; and a controller having a plurality of gate drive signal outputs, each being coupled to a respective one of said gate drives, said controller being configured to: generate, at said gate drive signal outputs, a plurality of gate drive signal sets for said gate drives; detect a fault status for a faulty inverter among said plurality of inverters; disable said faulty inverter in response to detection of said fault status; determine new operating parameters for a non-faulty inverter among said plurality of inverters; and generate an updated gate drive signal set for said non-faulty inverter, said updated gate drive signal set being influenced by said new operating parameters.
