摘要: | the proposed interleaving power factor correction (PFC) can effectively reduce the size of the AC-DC converter for portable electronics. Fully integrated variable sampling slope (VSS) technique can provide precise phase regulation under variable line voltage. Besides, the no-deadtime ramp generator (NDRG) records the previous status to modify the sequent on-time value to achieve current sharing for suppressing the total harmonic distortion (THD) and restraining the input current ripple, EMI filter, and the size of input inductor. Therefore, more power can be provided by the proposed interleaving PFC than that of single-phase PFC. Simultaneously, the drawback of the peak current twice than the average current in the Boundary control mode (BCM) can be greatly reduced. The test circuit fabricated in the TSMC 0.5 mu m 800V UHV process shows the highly integrated interleaving PFC can deliver high power of 180W with improved phase regulation precision. |
