Abstract

This paper proposes a new family of single-switching DC-DC converters. The proposed converters are based on the classical Zeta-converter combined with two versions of switched inductors/switched capacitors structures. Analysis of the circuits made it possible to choose the most effective variants in terms of increasing the voltage gain. A detailed analysis of the best of the proposed schemes allowed to obtain graphs of the dependence of the voltage gain on the value of the duty cycle in the continuous and discontinuous current modes. Values of voltage stresses on the semiconductor devices are estimated. Theoretical expectations are confirmed by experimental results.
