Abstract

This paper mainly introduces an interleaved boost high step-up dc-dc converter which is suitable to integrate a low voltage to a high voltage bus for renewable energy systems. The proposed converter achieves a very high step-up voltage gain by using two coupled inductors and voltage multiplier cell. The voltage stress on the semiconductor switches is significantly lower than the output voltage. The proposed converter can provide a high voltage gain with mitigating the voltage stress on the diodes. Furthermore, the reverse recovery problem of the diodes is mitigated, and the leakage energy is recycled. The topology can be operated without an extreme duty cycle or a high turns ratio. The aforementioned converter is fed by a single input voltage, and the mathematical expression is explored. The design, parameters selection, and experimental results are thoroughly introduced. A 24 to 768 V-dc is verified and simulated by using PLECS. Therefore, a 922 W hardware prototype is verified to validate the theory and the simulation results.
