Features
Maximum 400-W output power at 96 VAC–134 VAC grid connection
Two-stage converter achieving 92.8% plug-to-plug efficiency:
First stage: PFC interleaved Boost (97% efficiency) with UCC28064A, allows reduced EMI filter size and increases efficiency
Second stage: half-bridge resonant LLC converter (95% efficiency) isolates HV input, and supplies 30 V, 13.3 A
No need of an auxiliary power supply, since the second stage provides the bias voltage for the PFC
Specifically designed to comply with DO160-G harmonic limits in avionics applications for mains frequency in the 400 Hz–800 Hz range
