Efficient Charging of Ultracapacitors

Although ultracapacitors are very efficient devices for storing electric energy, methods for charging these capacitors can be very inefficient, dissipating an amount of energy (as heat) that is greater than the amount of energy ultimately stored in the capacitor. Researchers at Clemson are developing techniques for charging ultracapacitors that promise to improve the efficiency and reduce the electrical noise of systems that rely on ultracapacitors for energy storage.
