Abstract
Methods, systems and apparatuses for voltage regulation are disclosed. For an embodiment, a voltage regulator includes a power source block configured to convert an input voltage to an output voltage to supply current to an output load, a storage capacitor, and an active filter configured to transfer energy between the output load and the storage capacitor. A conversion ratio of the active filter is controlled by a parameter related to the output voltage, and a conversion ratio of the power source block is at least partially controlled by a parameter related to the voltage on the storage capacitor.
