摘要：

This paper proposes a method to measure the proximity losses of the Litz wire. A test bench is built to produce uniform alternating magnetic field in two air gaps. When the Litz wire are put into the air gaps, the proximity losses of the Litz wire are produced, and can be measured. Furthermore, the field density can be measured by a detecting coil. Then the curve of proximity losses versus field density can be finally obtained.
