Other Parts Discussed in Thread: UCC256304,
I have a high-voltage to 30 VDC 45 W application which may benefit from an LLC converter like the UCC25630x. The app notes and EVMs I see are all oriented toward a power factor correction (PFC) front end with pretty steady DC, but I'd like to know if the LLC would work with a rectified 60 Hz AC waveform and bulk capacitor instead. The peak and valley voltages of the waveform would be about 50 V apart, with peaks from ~350 to ~500 V.
I've seen one analysis which indicated good rejection of AC line frequency by this LLC, so it makes me think I could get away with this. Before I buy an EVM, though, I'd like to get some confirmation.
Thanks for any help!
