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.
