Sažetak
A new interleaved boost converter with high step-up gain is presented in this paper. The proposed topology integrates coupled inductors and floating-output capacitors technique into interleaved boost converter to provide high step-up voltage gain without extreme duty cycle.
The voltage stress on the power switches and diodes is very low, so low-cost and highperformance semiconductor devices can be employed. Also, the reverse recovery problem of all diodes is mitigated and zero-current-switching (ZCS) turn-on operation of the main switches is established as well. In addition, the passive clamp circuits are employed to suppress the voltage spikes across the main switches during turn-off instants. The operating principles and
steady-state analysis of the proposed converter in continuous condition mode are explained. Finally, the simulation and experimental results of prototype 25–400 V circuit with 200 W
output power are provided to verify the performance of presented topology.
