- © 2017 IEEE. This paper introduces a DC-DC converter topology with the following features: (i) quadratic voltage gain, which allows the converter to work with wide voltage line variations in a wide operation voltage range with a minimal variation of duty cycle and without the use of extreme duty cycles; (ii) output voltage ripple mitigation, this feature can be accomplished in a specific dury cycle by proper selection of components and PWM signals. The proposed converter can be designed to have zero output voltage ripple for the nominal gain (duty cycle), this allows the use of small values of capacitance. The operating principles and steady-state equations, for the discussed topology In CCM are presented in detail. Experimental teste are presented to validate the propositions.
