LOW FREQUENCY CONVERTERS HAVING ELECTROCHEMICAL CAPACITORS

摘要

In one embodiment of the invention, a low frequency converter is described that includes a first electrochemical capacitor to charge to an input voltage and a second electrochemical capacitor that is coupled to the first electrochemical capacitor. The second electrochemical capacitor is associated with an output voltage of the low frequency converter. Each electrochemical capacitor may have a capacitance of at least one millifarad (mF) and a switching frequency that is less than one kilohertz.
