High voltage gain DC-DC converter is a prime requirement for renewable applications, in particular for PV. Though numerous DC-DC converter is available for increasing the voltage gain, the passive elements requirement is higher which reduces the compactness, consequently, increases the cost of the system. To address this issue, a high gain DC-DC converter is reported recently. However, the number of passive elements is quite high which increases the size. To reduce the number of passive elements and maintain the same number of semiconductor devices, in this paper, a new switched inductor arrangement is proposed which is named as switched inductor double switch DC-DC converter (SL-DS-DC). Moreover, the proposed converter has a higher gain as compared to the recently reported converter. The proposed converter is analyzed in steady state and a comparative analysis is presented to prove the suitability. Finally, the proposed converter is validated experimentally.

Potential of bidirectional Split-Pi converter is yet to be exploited. Its unique features like bidirectional property, option to employ in multiphase systems and smaller ratings of passive elements provides liberty to use it in applications demanding high power density such as in hybrid electric vehicles, renewable energy, aerospace, military etc. In this paper dynamic model of Split-Pi converter is presented. State space averaging technique is used to derive the transfer function of Split-Pi converter operating in boost mode and type II compensator is designed for the stable closed loop operation of the converter. All the simulations of the converter are done using LTspice simulation software.
