Suitability of capacitive converters to photovoltaic systems

摘要

In this paper the connectivity of capacitive converters in general and General Transposed Series-Parallel converter in particular to photovoltaic sources is discussed. The paper describes the compatibility of capacitive converters to photovoltaic as soft sources since the voltage source can adjust itself to the change in the capacitors voltage and therefore reduces the inherent pulsating currents of switched capacitors converters when they are connected to rigid sources. The theory is demonstrated by simulation and the simulation results are in full agreement with the presented theory. The results show that if not better at least capacitive converters can be adequate interface with soft sources and their ability to be integrated makes this technology attractive.
