A modified High Gain SEPIC (MHGS) converter topology suitable for DC Microgrid has been derived from the SEPIC structure, with the intention of improving the voltage conversion ratio besides lowering voltage stress on the devices. To achieve this, a Switched Inductor (SI) cell has been used to replace the source inductor and a voltage multiplier network is added to the load side. Furthermore, intermittent capacitor of the SEPIC topology has been replaced with a power switch to maximize the voltage gain. The synchronous operation of the power switching devices in the proposed topology induces improved voltage gain. The Capacitor-Diode voltage multiplier network provides significant elevation in the output voltage. The proposed Modified High Gain SEPIC (MHGS) topology establishes continuous source current with reduced ripple. The proposed MHGS attains an elevated voltage gain of 90 at 80% of duty ratio. Steady state analysis, voltage stress expressions, power loss analysis and comparison with different converters are outlined elaborately. To assess the theoretical analysis, an experimental prototype is built with a specification of 200 V/100 W and the results are presented.
