Comparison of conventional and resonant boost converters for grid-connected solar systems

In photovoltaic sources, operating current and voltage, due to variable environmental conditions, will change. Since the operating point can maximize output power, one approach to use a maximum power point tracking seems to be necessary. Typically MPPT algorithms are implemented on a solar system utilizing a switching power converter. The used DC-DC converter in this paper is a boost; therefore choosing an adequate topology of boost converter is very important. In this paper resonant boost converters have been compared with conventional ones.
