Abstract
This paper proposes a new topology of a high step-up dc-dc converter for photovoltaic system applications. The proposed converter can boost up the low input voltage, about 20 V, generated from the PV array to the high output voltage level of approximately 400 V. The proposed converter employs only one power switch to achieve a high step-up voltage conversion ratio, approximately 20 times, without the extremely large duty cycle. The operating principles and steady-stage analyses of continuous conduction mode are described in detail. The relationship between the step-up voltage ratio and the duty cycle of the proposed converter is analyzed. The simulation and experimental results are shown to demonstrate the effectiveness of the proposed high step-up single-switch dc-dc converter for low-input and high-output voltage systems.
