A New Step-Up Converter With Coupled Inductor

The paper proposes a new step-up converter with coupled inductor, one active switch and three diodes that work as a Boost converter. Compared to the classical Boost converter, the novel topology provides a higher static conversion ratio at the same duty cycle. The proposed converter finds suitability in conversion where an output voltage much higher than the input voltage is required. A dc analysis is performed to obtain the static characteristic of the converter. Also, the design equations are provided, and the converter is simulated and experimentally tested in order to confirm the feasibility of the proposed step-up converter with coupled inductor.
