1. A power device comprising:

  • an input configured to receive input power;

    a controller coupled to the input and configured to;

    receive at least one sample of a voltage waveform of the input power;

    compare the at least one sample of the voltage waveform with a sinusoidal reference waveform to determine a plurality of offset values;

    compare each offset value of the plurality of offset values with a corresponding entry in a reference table; and

    shape an input current waveform of the power device to be substantially similar to the voltage waveform based on the comparing of the plurality of offset values to the reference table.
