Comparative study of zeta converter and a novel zeta converter with coupled inductor

Recently, inductor manufacturers have begun to release off-the-shelf coupled inductors. Consisting of two separate inductors wound on the same core, coupled inductors typically come in a package with the same length and width as that of a single inductor of the same inductance value, only slightly taller. The price of a coupled inductor is also typically much less than the price of two single inductors. The windings of the coupled inductor can be connected in series, in parallel, or as a transformer. In this paper a zeta converter is presented with coupled inductor and a capacitor multiplier in the secondary of coupled inductor to achieve high voltage gain.Open loop simulations of conventional zeta converter and the novel zeta converter has been carried out using MATLAB/SIMULINK and compared the performance of the two converters
