The solar charge controllers which are used to charge the batteries consists of DC-DC converters which are essential components in photovoltaic systems. There are wide variety of DC-DC converters which are used for different applications depending on their characteristics, but when it comes to battery charging applications generally transformer less converters are preferred as they are compact and suitable for low power applications. In the transformer less DC-DC converters there are different topologies, generally for battery charging applications and MPPT charge controllers the converters which has low output transients and fast response are preferred. In this paper the design and simulation of buck-boost, zeta and SEPIC converters are done and the comparison of their transient responses are obtained based on which a particular convert is selected for the given application.
