Method of extracting switching loss from a high efficiency MOSFET based half bridge converter

摘要: The measurement of losses in high efficiency / power converters is difficult. Measuring the directly from difference between input and output results large errors. Calorimetric methods are usually used to bypass this issue but introduce different problems, such as, long times, limited loss range and/or set up cost. In paper total a converter measured switching exacted. measurements can be taken with only three multimeters current probe standard bench supply. After acquiring two or versus sweeps, series curve fitting processes applied extracted.
