Abstract：In this paper,an improved interleaved boost converter topology with a high gain is presented. The currents of inductors are interleaved in parallel at input. The two output capacitors can be charged interleaving in parallel and discharged in series so that a high step-up voltage gain is achieved with an appropriate duty cycle. Moreover,the proposed converter structure can reduce the voltage stresses of active switches and diodes. The operating principle and the steady-state characteristics are discussed in detail to show the merits of the proposed converter,and the corresponding model is also derived. Finally,a 1kW rating prototype system is also constructed to verify the effectiveness of the proposed converter.
