摘要
In the paper investigations dedicated to development of measurement methods of power loss in fast semiconductor switches such as MOSFET or IGBT are presented. During the design of converters with high switching frequencies the estimation of switching power losses based on recorded switch current and voltage curves is difficult and does not provide adequate results. The method of quantitative measurement of semiconductor switch power losses with the use of thermal steady state picture registration is described and illustrated with laboratory result examples (Thermal measurement for verification of power loss in semiconductor switching devices)
