DC-DC converters with wide-bandgap semiconductors facilitate the operation at higher switching frequencies. Thus, inductors can be reduced in size which is beneficial in regard to power density and weight of the converter. As a drawback, high frequency inductors suffer from considerably large winding losses caused by skin and proximity effects. Litz wire is a possible solution but it results in a...
Measuring the dissipated power of fast switching semiconductors or magnetic components with low power factor makes high demands on the accuracy of the measurement equipment. Calorimetric measurement methods represent a possible solution for this problem but are considered as being too time demanding. A compensating temperature control facilitates to reduce the time demand for a single measurement...
