Accurate reactor evaluation in power electronics made easy
Roy Hali, Head of Product Management

High-frequency reactors, in combination with power electronic switching elements such as IGBT, SiC and GaN FETs, are used in a variety of solutions in electric vehicles (EVs) and hybrid electric vehicles (HEVs). Examples include step-up DC/DC converters, AC/DC converters, on-board chargers, etc. In the past, elements such as IGBTs were used as switching elements, and switching frequencies were on the order of tens of kilohertz.
In recent years, in the quest of reducing the size of above-mentioned converters and improving the power density of drivetrain, SiC and GaN switching elements are being used more often. As the switching frequencies of SiC and GaN elements are greater than 100 kHz, it is necessary to validate the performance and measure losses of switching elements as well as the reactors. By directly measuring reactor loss, as well as iron loss and copper loss ratios within reactor loss, you can significantly reduce research and development time and identify areas of improvement for reaching even higher efficiency and smaller form factors. In this presentation, Hioki will present a reliable and accurate solution for rector evaluation.
