A dual switched inductor-switched capacitor-based dc-dc boost converter evolution and analysis are presented in this article. The front-end converter with single inductor and switched capacitor provides a voltage gain similar to Quasi-Z-Source converter while the succeeding modified SEPIC based structure is embedded to enhance the voltage gain further. The output capacitor elevated peak current is abbreviated by reconfiguring the aforementioned topology. On this premise, two converters with common ground and continuous source currents are proposed in this article. A 400 V, 300 W, 50 kHz prototypes are developed to verify the performance indices in steady state analysis.
