Abstract

In this article, a new single-switch high step-up DC/DC converter with soft-switching performance is presented for sustainable energy applications. In this circuit, zero input current ripple is obtained at a small value of the input inductance. Therefore, the ohmic loss of the input inductor will be significantly alleviated. Also, a three-winding coupled-inductor (TWCI) and a voltage multiplier are merged in this topology to achieve high voltage gain with an appropriate duty cycle. Semi-trans-inverse specification of this circuit makes it possible to achieve high output voltages under a lower magnetic turns ratio, which leads to power loss reduction. Moreover, a regenerative clamp recycles the leakage energy to the output and also mitigates the maximum voltage stress across the power switch. In addition, to help further efficiency improvement, a resonant tank with a quasiresonant performance between the middle capacitors and the leakage inductance of the TWCI is adopted to decrease the power dissipations of the switching components. The operating principle and steady-state analysis of the introduced converter are described in detail. To verify the superiority of the presented circuit, a comparison with relevant converters is provided. Eventually, the theoretical analysis was verified by a 300-W experimental prototype.

期刊介绍： Energy Science & Engineering is a peer reviewed, open access journal dedicated to fundamental and applied research on energy and supply and use. Published as a co-operative venture of Wiley and SCI (Society of Chemical Industry), the journal offers authors a fast route to publication and the ability to share their research with the widest possible audience of scientists, professionals and other interested people across the globe. Securing an affordable and low carbon energy supply is a critical challenge of the 21st century and the solutions will require collaboration between scientists and engineers worldwide. This new journal aims to facilitate collaboration and spark innovation in energy research and development. Due to the importance of this topic to society and economic development the journal will give priority to quality research papers that are accessible to a broad readership and discuss sustainable, state-of-the art approaches to shaping the future of energy. This multidisciplinary journal will appeal to all researchers and professionals working in any area of energy in academia, industry or government, including scientists, engineers, consultants, policy-makers, government officials, economists and corporate organisations.
