Abstract
Universal electrical power conversion methods and systems which may provide the combined capabilities of symmetrical and asymmetrical conversion, bidirectionality, and simplicity are provided. In some cases, the converter charges an inductor connected in parallel between a regulated port and an unregulated port using energy stored by a capacitor positioned in parallel between the inductor and one of the ports until the inductor has a level of current stored that corresponds to the change in voltage desired at the regulated port, then discharges stored energy into the other port until a current cutoff threshold level is reached in the inductor. Creating an LC tank circuit during conversion allows conversion processes to traverse sinusoidal discharge patterns. In some embodiments, the inductor is precharged with current to affect the discharge of the inductor. Multiple ports can be connected and disconnected from the same inductor with these methods and systems.
