Abstract

This article introduces a new single active switch converter designed to achieve a substantial step-up ratio and dual output within a single stage by employing the Voltage Lift (VL) technique. This converter integrates two boosting topologies, namely a modified C´ uk converter and the quadratic boost converter (QBC). Both the Cuk and QBC converters have demonstrated their effectiveness and versatility in a wide range of applications, including uninterruptible power supplies (UPS), photovoltaic (PV) systems, wind power generators, fuel cell technology, automotive components, and telecommunications equipment. The proposed converter, QBCUK, employs the VL technique to achieve a high boosting ratio while maintaining a low duty cycle. This design reduces voltage stress on the main power switch compared to the recently developed QBC, thereby enabling the use of lower voltage-rated MOSFETs and reduced RDS(ON) values, ultimately leading to decreased conduction and switching losses. The article provides an in-depth comparison of the QBCUK converter with various QBC topologies introduced in recent research. The results of this comparative analysis clearly demonstrate that the QBCUK topology delivers a superior performance in terms of achieving a higher step-up ratio and output power across different duty cycles.
