A method and apparatus for generating an AC voltage with user defined inductance and resistance values in series therewith is described. The output voltage of the AC source is sampled and a signal indicative of the total current being generated is derived. The signal is scaled to model a series resistance and scaled and differentiated to model a series inductance. The modelled series resistance and inductance are then combined with the output voltage. Different inductances and resistances can be modelled merely by changing the user's input to the microcontroller that controls the operation of the present invention.
