Hi..........its amazing how a massive number of Power electronics company staff think that a burst mode SMPS is worse at EMC , than a standard frequency compensated SMPS.....which if course, is totally not true....neither does it fail flicker.

I once worked at a co, where they had a 600W UV lamp, which was on a gantry going back and forth, every time it hit the gantry end, the 600W was suddenly turned off, then suddenly turned back on again some 2 seconds later......the full load transient made the output go up to >60V.....and it eventually blew up the control PCB.......they were asked why they didnt use a Burst mode SMPS....which would have alleviated the problem....they said , because Burst Mode would fail EMC....which of course, is nonsense...they are pretty much just the same at EMC as a standard frequency compensated SMPS.

(ayk, a Burst mode smps, which has a hysteretic comparator at output for regulation.....has a certain fixed peak current setting.....if you incrementally increase its load...you will eventually get to a stage where its output drops a little , and it goes into continuous mode..not bursting.............if you use it for a power level which is just a bit lower than dropout, then it is in burst mode, but its peak current level is pretty well the same as what you'd get with a frequency compensated SMPS.)

So do you agree....Burst mode is set for a big return?
