Abstract

With the current problems encountered by the conventional sources of energy, photovoltaic (PV) is a very useful and friendly source of renewable energy. Normally, photovoltaic provides low voltage level and it is usually not enough to supply the voltage level required at the load. In this work, three DC-DC converter topologies are presented to regulate the power extracted from the PV, which are highly suitable for renewable energy application that requires high ratio of DC – DC conversion. When benchmarking the traditional converters to the proposed one, the new designed 2LC-Y has been found to be superior in many aspects. Such as, the new designed 2LC-Y converter can provide higher output voltage comparing to the old ones, even though it uses less reactive components and less number of devices, which consequently reduces the complexity of the designed circuit. The results obtained from the simulation have shown that, the designed 2LC-Y converter requires only a single switch to control it. Furthermore, it has the ability to obtain negative output voltages by the use of non-isolated topologies. Also, it doesn’t require the use of high duty cycle in order to achieve high conversion ratio as other available converters in the literature. Promising results have been obtained to support the validity of this new generation of 2LC-Y converters.
