This has nothing to do with LEDS
Many power converters are liable to saturate the transformer under unbalanced conditions, I am looking at a full bridge with a bridge rectifier output so there are plenty of oppertunities! The standard method to reduce the problem is to use peak current control. In my case I wish to use average current mode, a typical LPF plot for a 25Khz converter is shown in the attachment (this is currently (pun) running a half bridge). What I am having trouble getting my head around is given the LPF somewhat inhibits cycle by cycle current limit will ACM still prevent flux-walking and potential saturation ?
BTW the target is 3Kw through an ETD54 at 50Khz
PS I dont mean to be asking a yes/no question, rather has anybody working knowlage in this area they care to share ?
