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 half-bridge isolated DC/DC converter. Comparison of calculation and experimental...
In this paper the light load operation of 6.5 kV 200 A IGBT modules in half-bridge configuration is analyzed. The study consists of an experimental and an analytical part. The experiments were carried out on a 40 kW high-voltage half-bridge isolated DC/DC converter. Studies focused on Infineon FZ200R65KF1 IGBT modules. In the analytical part, the static and dynamic losses of IGBT modules at different...
This paper discusses the half- and full-bridge DC/DC converter topologies for high-power (200 kW) high-voltage (3.6 kV) applications. Focus is on the primary part of these topologies, i.e. the feasibility of two high-voltage IGBTs replacement in the full-bridge by two high-voltage film capacitors in the half-bridge.
