An efficient high-step-up interleaved with a common active clamp DC-DC converter for electric vehicle

Abstract

This paper aims to present a high-step up and non-isolated interleaved dc-dc converter with a common active clamp circuit which makes it highly efficient. The proposed DC-DC boost converter is used as an electronic module for electric vehicle application. Due to the collection of recycled leakage energies collected in a clamp capacitor, it is then recycled to separate load by the clamp boost converter to achieve high efficiency. In addition to this, it avoids mitigation of the output diode's reverse recovery problem and also achieves reduction of voltage stress thereby interleaving the converters. A boost converter is used to clamp the voltage stresses of all the switches in the interleaved converter which is caused by the leakage inductances.
