Abstract
In this paper, a high step-up DC-DC boost converter is introduced, which utilises the coupled inductor and switched capacitor techniques to increase voltage gain, adjustable by changing the turn ratio of the coupled inductors. Additionally, the leakage inductance of the coupled inductors reduces the reverse recovery problem of the output diode. The boost inductor in the input stage ensures continuous input current, thereby extending the lifetime of the input battery or improving the performance of renewable power sources. The proposed converter employs an active clamp technique to achieve soft switching for both the main and auxiliary switches over a wide range of output power, ensuring zero-voltage switching during both on and off states. Key features of the proposed converter include continuous input current, soft switching, high voltage gain, and a simple structure. A 200 W laboratory prototype is implemented, and the results are provided.
