CONTROLLER FOR A MULTIPHASE INVERTER

The present application relates to a controller arrangement for controlling an inverter (203) for converting an input power (202) from a power source (201) to a multiphase AC output power (205) provided at a power output (204) of the inverter (203). The power output (204) is connected to a load (212) and additionally to a power grid (214). The controller arrangement includes a signal input (222) for receiving a power signal (223) per phase representative of at least one of the power per phase provided to the load (211) or the power per phase provided to the power grid (210). The controller arrangement is further adapted to control each phase of the multiphase AC output power (205) individually according to the corresponding power signal (223). The invention further relates to an inverter comprising such a controller arrangement, a power distribution arrangement comprising such an inverter and a controller arrangement to control the inverter and the invention further relates to a method for controlling such an inverter.
