Hi, I'm trying to build a switched mode power supply that:
-outputs regulated 200v dc, although the exact voltage doesn't really matter, 100-400v is good, as long as it stays constant (little voltage ripple)
-outputs 700w continuous (also having a surge power capability of 1500w would be even better)
-runs off of 115v ac mains (having the option of use it off of 230v mains would be nice too)
-must have a power factor of >0.9, >90% efficiency, and cannot trip a 15A circuit breaker - to provide 1000w of burst power, it might have to store some power for a fraction of a second to provide that burst without tripping the breaker
This is to provide power for a custom audio amplifier I'm designing, so it would obviously have to provide big bursts of power, up to 2x the continuous power rating
Would a PFC chip like this https://www.ti.com/lit/ds/symlink/ucc28019a.pdf be what I'm looking for? Then I could just make a standard switched inductor based voltage regulator to reduce the ripple further? Any help would be appreciated, I've been researching for quite a while now.
