High-frequency transformer is a critical part of a switching mode power supply. How to measure the high-frequency noises of a trans-former is becoming a hard problem of the industry when the switching mode power supply is becoming more and more high-frequency. Proposes an ultrasonic measurement system for the high-frequency transformer. It can measure the ultrasonic wave which is out of the range of human being, processes and analyzes the measured data in the microchip, then displays the average power class of the selected frequency band of the high-frequency noises on the screen.
