Abstract

Summary: This article proposes a new Zeta‐based switched‐capacitor (SC) dc‐dc converter, which has many advantages such as increased voltage gain, decreased duty‐cycle, lower voltage stress on components such as its capacitors and input switch, and increased output power over traditional dc‐dc converter structures. In traditional converters such as Zeta converter, there is only one coupling capacitor, which works as a medium for transferring the power between input and the output. However, in the proposed Zeta‐based converter, there are multiple coupling capacitors, which are used based on dc‐dc SC converter principles. By using these switched coupling capacitors, the mentioned advantages are obtained for the proposed structure, which in turn make this converter more applicable for industrial applications. The analysis has been validated by comprehensive and precise comparisons and experimental results. Abstract : This article proposes a new Zeta‐based switched‐capacitor (SC) dc‐dc converter, which has many advantages as increased voltage gain, decreased duty‐cycle, lower voltage stress on components, and increased output power over traditional converters. In traditional converters like Zeta, there is only one coupling capacitor, which works as a medium for transferring the power between the input and the output. However, the proposed Zeta‐based converter possesses multiple switched coupling capacitors, which make it more applicable for industrial applications with high power ratings.
