| Abstract |
This paper focuses on the evaluation of the calculated and measured values of high-voltage 6.5 kV IGBT module losses, used in mid-power applications under low load conditions. The values of the losses were calculated by use of widely known equations and IPOSIM 6.0 software. The experimental setup was based on a high-voltage halfbridge isolated DC/DC converter. Comparison of calculation and experimental results shows that the dynamic losses on higher switching frequencies are smaller than those calculated and that the IPOSIM software is relatively accurate. This knowledge helps developers to avoid overestimation of the losses and allows us to construct more compact power electronics applications with much higher switching frequencies. |
