Abstract
According to various aspects and embodiments, a power device is provided. The power device includes an input configured to receive input power, and a controller coupled to the input. The controller is configured to sample a voltage waveform of the input power, compare the sampled voltage waveform with a sinusoidal reference waveform to determine a plurality of offset values, and shape an input current waveform of the power device to be substantially similar to the voltage waveform based on the plurality of offset values.
