Abstract:
The present examples relate to a power factor correction device, a power factor correction method, and a corresponding converter, in which when an input signal inputted into the converter is changed, a reference signal is also changed to fit to the input signal in consideration of only the frequency and the phase of the input signal. Thus, even without a specifically designated control circuit, examples make it possible to improve power factor correction and Total Harmonic Distortion (THD) and to reduce the size of a semiconductor chip, and examples are potentially used for a device receiving waveforms other than a sine wave.
