Hi Everyone
I was reading papers about buck converters control systems and come across the term, small signal analysis, can anyone tell me what that actually means ?
Regards,
Jeffrey

| It means an ac simulation of a small input signal (e.g. 1mVeff) around a fixed DC operating point. Mostly used for gain/phase vs. frequency, gain vs. DC operating point, output impedance measurement etc.

| When having small variation of the voltage / current, small signal circuit analyses might apply where the transistors can be considered linear
