The invention provides a method of controlling a voltage, the method comprising providing an alternating current waveform input to voltage controlling apparatus, rectifying the input to give a single polarity waveform, feeding the single waveform to a waveform chopping stage, feeding the output of the waveform chopping stage to the primary coil of a transformer, the output of the secondary coil of the transformer forming the output waveform of the method. Advantages in terms of the weight and efficiency of voltage control units result. <IMAGE> |
