Abstract
With the advent of distributed generation (DG), the need for efficient power electronic converter is increasing as the incorporation of renewables with battery unit and loads rely heavily on them. This paper suggests an original structure of high-gain DC to DC converter named as "Two-Tier converter" with the reduction in voltage stress. The configuration is resultant of stacking two-stage of the classical boost converter. The voltage gain offered is high for even lower values of duty cycle as the relation of gain is quadratic. Also, the converter current at the input is continuous, and the load configuration offered is grounded. Analysis and operational modes of the proposed converters and effect of the effective series resistance of inductors on voltage gain are presented in detail. A comparative analysis of suggested and new high-gain converters is presented in detail. The suggested configuration is confirmed using detailed simulation studies.
