The paper presents a two-phase interleaved boost converter (IBC) providing higher step-up conversion ratio compared to the conventional IBC. The circuit consists of a crossly connected diode-capacitor cell which provides the extra boost up. The two identical capacitors of the cell are charged in parallel and discharged in series providing high voltage gain at considerably low duty ratio. Switching operations, ripple and average currents through inductors are analyzed in continuous conduction mode (CCM). Ripple in input current is also improved. The voltage stress across the semiconductor devices is less in the proposed converter. Also, boundary load condition is derived. Small-signal modeling is carried out and a control circuit is enabled in the voltage mode control framework. Power losses are analyzed and 96.53[Formula: see text] efficiency is achieved. Finally, the proposed converter is designed and implemented, and experimental results are provided.
