To perform the measurements, you inject a small AC signal into the power supply’s control-loop circuit and measure the loop’s gain and phase shift. By measuring the gain and phase, you can plot them ...

A: Bode plots compare input-output signals, and are thus a representation of a system’s transfer function. Like all ratios they prefer a log-base notation because it simplifies the manipulation ...

Using my Multisim SPICE tool to analyze an oscillator, I ran into a little bit of simulation trouble. My circuit was a simple Colpitts oscillator and the simulation showed that it would indeed ...

A frequency response analyzer (‘FRA’) is often used to measure gain and phase plots of control loops (Bode plots), filter responses and general frequency domain transfer functions. The FRA ...

3rd course in the Power Electronics Specialization Instructor: Robert Erickson, Ph.D., Professor This course teaches how to design a feedback system to control a switching converter. The equivalent ...
