The main theme of this paper is to present a robust controller for digital-controlled power converters. The controller design and digital implementation to robust control to achieve robustness to load disturbance while retaining steady state performance of digital-controlled buck converter are presented. The robust controller is designed based upon two-degree-of-freedom control law. The specifications...
The objective of this paper is to present an on-line parameter tuning technique for digital power converter with predictive peak current mode control operating in boundary conduction mode. The issues caused by both inductor variation and input voltage drift can be solved by the proposed on-line parameter tuning technique which is based upon the sampled currents between two PWM outputs. The proposed...
The objective of this paper is to present an online parameter tuning method for digital power converter with predictive current-mode control. The proposed method can effectively deal with the issues caused by variation of inductance, input voltage drift, and voltage drop caused by DCR. The proposed online parameter tuning method is based upon adding an additional current sampling between two pulsewidth-modulated...
