Application Notes
- UCC28070 300W Interleaved PFC Pre-regulator Design Review (Rev. B)PDF, 753 Kb, Revision: B, File published: Jul 8, 2010
In higher power applications to utilize the full line power and reduce line current harmonics PFC Pre-regulators are generally required. In these high power applications interleaving PFC stages can reduce inductor volume and reduce input and output capacitor ripple current. This results in smaller overall magnetic volume and filter capacitor volume increasing the converters overall power density. - UCC28070 Implement Bridgeless PFC Pre-Regulator DesignPDF, 739 Kb, File published: Jun 18, 2009
Bridgeless power factor correction (PFC) topology is attracting attention as a means of satisfying the new high-efficiency requirements. This application report reviews the UCC28070 and its design considerations for bridgeless PFC. It present a bridgeless solution that is relatively easy to implement in that it does not require any additional circuitry for current sensing and that the operation re
