This paper presents a buck converter augmented with additional energy paths that enable a near null response to load transients. Fundamental performance limits, such as slew-rate limits, are overcome resulting in increased bandwidth with a response that is faster than previously established “minimum time” or “time optimal” control of conventional buck converters. An energy-based method is presented...
This paper presents the concept of a voltage controlled pulse skipping modulation (VCPSM) in a dc-dc converter, which improves the efficiency, ripple magnitude, and transient response over a wide range of light load condition. The duty ratio of VCPSM, instead of remaining constant as in a classical PSM, is controlled using the voltage mode control with an additional input voltage feed-forward along...
This study proposes a nonlinear control method for improving the energy exchange between a structure and actuators. A modal development of the control and the mechanical work of actuators emphasizes independent "stiffness actions" and "damping actions". This paper deals with the improvement of stiffness actions for which emulated strain energy is accumulated by actuators and then...
