This system uses closed-loop methods to generate a reference potential based on the output waveform. For determination of direction, the output waveform should be high for 50% of the total cycle and low for 50% of the cycle. However, the present method may be used for any constant need of symmetry of the output signal. The basic operation of the present method is to examine the output signal during one or more cycles, and determine the amount of time the signal is high and the amount of time the signal is low. These two times are compared to the objectives, and the reference potential adjusted, if needed.
