Opis:: The purpose of the article is a comparison between DC/DC topologies with a wide input voltage range. The research also explains how the implementation of GaN E-HEMT transistors influences the overall efficiency of the converter. The article presents a process of selection of the most efficient topology for stabilization of the battery storage voltage (9 V – 36 V) at the level of 24 V, which enables the usage of ultracapacitor energy storage in a wide range of applications, e.g., in automated electric vehicles. In order to choose the most suitable topology, simulation and laboratory research were conducted. The two most promising topologies were selected for verification in the experimental model. Each of the converters was constructed in two versions: with Si and with GaN E-HEMT transistors. The paper presents experimental research results that consist of precise power loss measurements and thermal analysis. The performance with an increased switching frequency of converters was also examined.

Opis:: This paper focuses on the analysis of a power factor correction (PFC) converter using close loop Ĉuk topology. Regardless of the input line voltage and output load variations, input current drawn by the buck or buck-boost converter is always discontinuous. The Boost converter suffers from high voltage stresses across the power electronic devices. The input current in Ĉuk converter is comparable to boost converter’s input current. In this paper output voltage is controlled by inner current and outer voltage control loop along with power factor correction (PFC). It shows less input current THD (less than 5%), nearly unity power factor and better output voltage regulation of AC-DC converter under variable input voltage and output load. Small signal model analysis is presented for obtaining frequency response of the control loop. The MATLAB Simulink programming environment is used as a simulation tool.
