Beschreibung
This is a compact, 30-V DC, 400-W reference design for avionics applications, accepting main frequencies between 400 Hz and 800 Hz. This design consists of a front-end, two-phase interleaved transition mode (TM) power factor correction (PFC) based on UCC28064A. This minimizes the PFC inductor size and reduces EMI filter requirements. The DC/DC is implemented by employing HB-LLC stage, using UCC256404. For efficiency improvement, synchronous rectification is used at secondary side with FETs driven by UCC24612.
Eigenschaften
- Overall efficiency of 92.5% at full load with peak efficiency > 93%
- High power factor > 0.99, meets PFC regulations and current THD for DO-160 avionics requirements
- ZCS avoidance feature and OVP sensing feature in LLC controller improves robustness and protects systems from overcurrent, short circuit and overvoltage to ensure safety
- Small PCB form factor of 160 mm by 80 mm by 30 mm
Typische Anwendungen
- Full authority digital engine control (FADEC), Standalone avionics PFC
