Notas de aplicación
- UCC28070 Implement Bridgeless PFC Pre-Regulator DesignPDF, 739 Kb, Archivo publicado: 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
