In this paper, a practical analog implementation of capacitor charge balance controller is presented, which is capable of achieving the optimal response for dc-dc Buck converters without relying on the knowledge of the nominal passive component (output inductor and capacitor) value. This ready-for-integration analog controller applies the output voltage curve analysis for deriving the formulas to...
A hardware efficient optimum-deviation voltage mode controller with a fast and noise-insensitive detection of the key voltage waveform points during load transients is introduced. To reduce the effects of noise and delays on the detection, a two extreme point detector with a voltage tracking window is introduced. In addition, an on-line algorithm for the compensation of load-dependent duty ratio variations...
