Abstract

A method of controlling an inverter for converting a DC input to an AC output, the method including measuring a voltage of an AC output produced by the inverter; determining a drive voltage for controlling the inverter; and if a difference in amplitude and/or phase between the drive voltage and the measured voltage exceeds a predetermined threshold, modifying the drive voltage to reduce the difference in amplitude and/or phase between the drive voltage and the measured voltage. The method may be particularly useful for controlling an inverter during "islanded" operation with a variable load, and may therefore be useful e.g. in marine, battlefield, disaster-relief and/or aviation electrical power systems.
