A control system for a DC to AC inverter (26) is disclosed, the control system comprising a reference signal generator for generating a reference signal having a waveform representing a desired output signal, and control means for controlling the inverter such that the waveform at the inverter output substantially corresponds to the waveform of the reference signal. The control means operates at least in part in dependence on the current at the inverter output. The system also includes determining means for determining a measure, such as an RMS value, of the output of the inverter, and adjusting means for adjusting the amplitude of the reference signal in dependence on the measure of the inverter output. This can allow variations in the output of the inverter to be corrected.
