WebConclusion. This article presents a general analysis framework for modeling and control for a current-mode buck converter with a secondary-stage LC output filter. The accurate control-to-output transfer function is discussed. A new hybrid feedback structure is proposed and the feedback parameter limitation is deduced. WebOct 1, 2024 · The dynamics of any control loop are governed the components involved. The purpose of "compensation" is to avoid building an oscillator from an amplifier. This can happen when the loop gain exceeds unity AND the phase shift is any multiple of 360°. This is usually accomplished by adding phase shift in the vicinity of the unity gain crossover. N.B.
