Novel high step up DC/DC converters with reduced switch voltage stress

In this paper, a novel step up DC/DC converter with reduced switch voltage stress is introduced firstly. The proposed converter is analyzed in steady state and is compared with other DC/DC converters with equal number of components. The voltage stress on all switches is lower than the output voltage. Then, it is shown that the voltage transfer gain can be increased considerable by replacing one of its inductor with two types of switched inductor voltage multiplier cell. Therefore, high step up switched inductor DC/DC converters are realized. The operations of the proposed converters are verified using the simulation result
