Trends (Improving Performance)

Output power density (kW/dm3) Efficiency Output power per unit weight (kW/kg), Output power related to costs (kW/$) Failure rate

Dependency of the power density on the switching frequency

Improvement of the power density

Trends (Applications) Energy Storage, Supercapacitors

Supercapacitors in 4, 10, 100, 450, 900, 1800 and 2600 Farad sizes are available The rated voltage will be increased up to 3V within the next years
