Abstract:
A power converter comprising:a power output stage including a load capacitor and a fly capacitor, the fly capacitor comprising an ultra-capacitor, the power output stage configured to receive an input voltage from an energy source and to provide an output voltage across output terminals, the load capacitor being electrically coupled across the output terminals, the power output stage further configured to switch between a charge state and discharge state, wherein the charge state includes the fly capacitor being electrically in parallel to the input voltage and wherein the discharge state includes the fly capacitor being electrically coupled across the load capacitor; and, a clockless dynamic controller operably coupled to the power output stage and adapted to respond to the output voltage across the load capacitor and to a predetermined reference voltage to command the switching from the charge state to the discharge state wherein the clockless dynamic controller commands switching between charge and discharge states at a predetermined slew rate.
