Charging a supercapacitor from a 5V USB port may seem simple at first, but to charge three supercapacitors to 7V and to limit the input current to the 500 mA maximum limit on the USB port is somewhat ...

In Part 1 of this series, we have reviewed solar cell performance, how to select and size the supercapacitor, requirements of supercapacitor charging circuits and charging IC characteristics. We will ...

As the cost to produce supercapacitors (SCAPs, or ultracapacitors) continues to decline, they are carving out a niche in the marketplace between conventional capacitors and batteries. And, although ...

How to build a photovoltaic light system that operates at all times and is maintenance-free. The key role of the supercapacitor in this design. What is the "Joule Thief" circuit? Delivering ...

One of the biggest challenges for wireless sensor networks is that of power. Solar panels usually produce less power than you hoped, especially small ones, and designing super low power circuits is ...

So far our discussion summarizes the fact that in practical electronic systems a combination of different DC-DC converter topologies are used to achieve the overall efficiency, noise minimization, ...

Researchers at UCLA have developed a new method for growing PEDOT nanofibers with exceptional energy storage capabilities. “The advance could lead to supercapacitors that can meet some energy storage ...

Andrew F. Burke has been called the Saint Paul of supercapacitors, evangelically spreading the word about the potential use of the energy-storing devices in hybrid and electric vehicles. A research ...
