Measuring a Buck Converter's Open-Loop Response

 This example shows how to apply the double-cross spectrum transfer function measurement technique to a buck converter, a type of switched-mode power supply. You can apply this measurement technique without breaking the loop and without concern over whether the open-loop response is stable. Only the closed-loop system needs to be stable.
