In boost converters and other indirect energy transfer topologies, transient-oriented controllers are designed to facilitate a dynamic response that may range from minimum time up to minimum output voltage deviation. Since analytical definitions for these control laws can become quite complex, a large-signal stability verification is not immediate. This(More)
A resonant switched capacitor converter with high efficiency over a wide and continuous conversion ratio range is introduced. The efficiency of the topology depends primarily on the conduction losses and is decoupled, to a large extent, from the voltage conversion ratio. This is an advantage over classical switched capacitor converters, for which the(More)
This paper introduces an active method for zero current switching for resonant switched capacitor converters (SCC) with wide dynamic range. The method is demonstrated on a binary SCC that features wide range of conversion ratios. Due to the resultant high efficiency of the converter operating under soft-switching conditions, it is applicable for higher(More)
A new, small and efficient voltage regulator, realized using a resonant switched-capacitor converter technology, is introduced. Voltage regulation is implemented by means of simple digital pulse density modulation. It displays an ideal transient response with a zero-order nature to all disturbance types. The newly developed topology acts as a gyrator with a(More)
A discrete time-domain based system identification method for PWM DC-DC converters is presented. The proposed procedure is capable of successfully reconstructing the system’s model from an arbitrary excitation at the command input. In this study, a step perturbation was applied, which is simple to apply and has an intuitive interpretation of the output(More)
The closed loop response of voltage feedback converters was re-examined theoretically and tested by simulations and experiments. It was found that the classical second order representation of the closed loop response of a PID controlled system is incomplete due to the contribution of previously neglected factors, such as a closed loop zero and low loop(More)
