Abstract

See full text

Systems and methods for protecting the redundancy of inverter blocks are provided. In one example implementation, a system can include a plurality of inverter blocks. Each inverter block can include a first conversion entity configured to convert DC power to AC power, a second conversion entity configured to convert AC power to DC power, and a third conversion entity configured to convert DC power to AC power. An isolation transformer can be coupled between the first conversion entity and the second conversion entity. The system includes an inverter block switching element coupled to an output of each inverter block. A protection element is disposed in each inverter block. The system includes one or more control devices configured to isolate at least one of the plurality of inverter blocks based at least in part on a status of the protection element disposed in the inverter block.
