Limitation of Switching Frequency to Improve Characteristics and Suppression of Input Current Distortion for Critical Mode PFC

In critical mode power factor correction (PFC), the switching frequency is varied to achieve a sinusoidal input current waveform. Under certain conditions, a higher frequency increases the loss and noise. Meanwhile, the limitation of the switching frequency leads to an increase in input current dist...
