94.5% Efficiency, 24V @ 21A – 500W industrial AC-DC reference design

https://www.electronics-lab.com/94-5-efficiency-24v-21a-500w-industrial-ac-dc-reference-design/

This reference design is a compact, high efficiency, 24-V DC, 500-W reference design for industrial AC/DC power supplies. This design consists of a front-end, two-phase interleaved transition mode (TM) power factor correction (PFC) based on the UCC28064A. This minimizes the PFC inductor size and reduces EMI filter requirements. The DC-DC is implemented using the HB-LLC […]
