Introduction
This application note provides a design for charging supercapacitors using either dedicated supercapacitor chargers or simple modifications to Li-ion battery chargers. The main idea is - to make a device similar to solar powered power banks, but instead of Li-Ion batteries, use supercapacitors. Supercapacitors, also known as ultracapacitors or double-layer capacitors, are high-capacity electrochemical capacitors with capacitance values much higher than other capacitors. They store 10 to 100 times more energy per unit volume or mass than electrolytic capacitors, can accept and deliver. Not only that, but this passive element has unlimited charging cycles, which means it lasts for a long time. These capacitors will easily pass 1500 Amps and would look like a short circuit if just connected to the DC bus - resulting in welded breakers, likely damage to the inverter (s), fire, death, etc.
