Abstract:

 In this thesis, a boost converter operating all the switching devices under ZVT is studied and a model converter is used in the Solar Energy systems using PV array and MPPT algorithm. Generally photovoltaic (PV) energy systems are gaining popularity because the systems are being developed to extract maximum energy from the sun in most efficient way and feed it to the loads without affecting their performance. The efficiency of a single PV cell is very low. In the proposed converter topology, a part of the circuit resonates for a small period of the switching cycle of the converter, known as the auxiliary resonant circuit that provides the soft transition from ON state to OFF state and vice versa, thus by reducing the losses that occur due to hard switching of the switches converter efficiency can be improved. Due to reduced losses during switching transitions heating effect of MOSFETs is reduced and have a longer life. The comparative study between the proposed topology and conventional hard switching converter can be analyzed in terms of reduction of switching losses and the improvement of efficiency.
