It simply can never oscillate because there is no feedback loop. The correction may be slightly imperfect giving less than optimum regulation, but it will be totally and unconditionally stable.   Thanks for the detailed reply again Tony, I need to articulate myself more when I post, the query about stability was directed at the current sensing compensation which I reckon is a feedback loop of sorts in that we sense current adjust the output, which affects the current which effects the output....stop I want to get off. There is no doubt in my mind that feedforward compensation for the input voltage should be unconditionally stable. If at first you dont succeed, I suggest you avoid sky diving.... Cheers Mike
