A BL configuration of Cuk converter is proposed which eliminates the usage of diode bridge rectifier at the front end of the PFC converter, thus reducing the switching and conduction losses coupled with it.

WebMar 15, 2024 · In Figure 2 (b), a single booster after the diode bridge, as in a conventional single-phase PFC, yields unacceptable harmonic distortion, about 30%. It is necessary to actively shape each phase current. One of many ways to accomplish this is to add back-to-back FETs connected between each line inductor and a split DC link, as in Figure 3 (a). WebThe conventional boost topology is the most efficient for PFC applications. It uses a dedicated diode bridge to rectify the AC input voltage to DC, which is then followed by …
