Supercapacitors in power converter DC link: A short overview of design and application issues

Very high values of efficiency in electric power conversion, electric energy saving requirements and power converter component optimization are priorities in design and construction of any type of modern power electronic converters. Moreover, if such power converters are connected to battery power source or other "weak" power source (as, for instance, fuel cells), additional design problems appear in sense of (battery) power source longevity, absorption of high peak power transients, provision of on-demand power bursts for load and other. EDLC, well known by their commercial name as Supercapacitors, are one of the possible solutions for aforementioned problems.
