Overview
| Topology | LLC Resonant Converter |
| Input voltage | 200-260 V |
| Switching frequency | 0.4-0.8 kHz |
| Output 1 | 30 V / 13.3 A |
| IC revision | 1 |
Description
This is a compact, 30-V DC, 400-W reference design for avionics applications that works with mains frequency between 400 Hz and 800 Hz. A two-phase interleaved transition mode (TM) power factor correction (PFC) based on UCC28064A is used to correct power factor and minimizes harmonic content of input current. The DC/DC is implemented using the HB-LLC stage with UCC256404. Efficiency is further improved by using synchronous rectification on the secondary side.
Features
- Overall efficiency of > 92% at full load with 92.8% peak efficiency
- 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 improve robustness and protect systems from overcurrent, short circuit and overvoltage to ensure safety
- Board dimensions of 218.44 mm x 102.26 mm, height = 31.75 mm
Typical applications
- Aircraft cockpit display
- Power conversion system (PCS)
