      In digitally controlled dc-dc converters with a single voltage feedback loop, the two quantizers, namely the analog-to-digital (A/D) converter and the digital pulse-width modulator (DPWM), can cause undesirable limit-cycle ...
    • Proximate time-optimal digital control for synchronous buck DC-DC converters 

      Yousefzadeh, Vahid; Babazadeh, Amir; Ramachandran, Bhaskar; Alarcón Cot, Eduardo José; Pao, Lucy; Maksimovic, Eduard Alarcón And Dragan (Institute of Electrical and Electronics Engineers (IEEE), 2007-07)

      This paper introduces an approach to near time-optimal control for synchronous buck dc-dc converters. The proposed proximate time-optimal digital (PTOD) controller is a combination of a constant-frequency pulsewidth ...
