Abstract:
Nowadays developments are occurring in the field of sustainable energy sources.
Sustainable energy sources like photovoltaic systems and fuel systems require differ
ent levels of power supplies. Traditionally, transformer or inductor based multiport
dc-dc converters were used. But these converters have high electromagnetic interfer
ence and are larger in size. In this seminar report, a level shifting switched capacitor
voltage copier circuits with feedback control is introduced with less number of com
ponents. There are five circuits namely summation, subtraction, double, half and
inverting circuits. The concept is further extended. A small resonant inductor is
introduced to limit the switching current. Thus zero current switching is achieved.
Simulation has been carried out to study the performance of the proposed topology
in MATLAB/SIMULINK environment. Simulation results are analysed and results
are presented for circuit.
