Modelling of a converter in an energy storage system with parallel working units

In the paperwork models of converters for energy storage elements have been developed. The models are made by using the software: LTSpice and Matlab. The results from the studies are compared with results obtained from a real experimental model. Specific output circuits for supercapacitor cells charging have been modeled. These models are applicable in different power circuits for similar applications. When a large number of specific parameters in the models must be taken into account the model can be further developed.
