Abstract: In this paper, certain non-isolated high step-up DC-DC converter topologies operating in continuous conduction mode (CCM) are reviewed. The review is presented based on the voltage gain, voltage–current stress of the power switches and diodes, the number of passive components, the efficiency, and the types of configurations. The DC-DC converter topologies considered for review are compared in terms of voltage gain pertaining to CCM for duty ratio k = 0.6. The simulation results and discussion are explored for a diode rectifier-fed high gain quadratic DC-DC converter configuration.
Keywords: CCM, DC-DC converter, Duty ratio, Quadratic converter, Voltage-current stress, Voltage gain.
