摘要：
The results of research conducted to determine the power losses in transformers used in power electronic in which the instantaneous values of transformed voltages have a square shape with frequency of tens of kHz were presented. A method of heating core and windings in use direct current (DC), to obtain a thermal characteristics to estimate the power losses of the windings of the transformer was proposed. The results obtained from the proposed method were compared with analytical calculations for planar transformer 4800VA/100kHz. (The thermovision method for windings power losses assessment of high frequency planar transformer).
