Placement of compensation capacitor
Hi rtarbell, I''d say the primary reason this is not usually done is because of stability. Q4 introduces extra phase shift that reduces the phase margin of the miller stage. In either configuration, the slew rate is primarily limited by the supply current of the stage driving Q3''s base, rather than the collector current of Q3, so including Q4 in the loop …
Model Predictive Control of an Active Capacitor for Ripple Energy ...
In order to reduce the ripple current and simultaneously reduce the size of the electrolytic capacitor, a DC - to - DC boost converter is employed. The capacitor of the DC-to-dc boost converter, the active capacitor, is used for ripple energy compensation. This paper presents a model predictive control (MPC) strategy of the active capacitor.
