- Limitation of Switching Frequency to Improve Characteristics and Suppression of Input Current Distortion for Critical Mode PFC
抄録
<p>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 distortion. This paper proposes a method to prevent an increase in distortion by compensating the pulse width at a limited frequency. Using this control method, critical mode PFC with a limited maximum switching frequency was evaluated. As a result, the total harmonic distortion of the input current was lowr than that before the frequency limitation. Furthermore, the improvement in efficiency and the reduction in conducted EMI were confirmed.</p>
