Using a reconfigured common-mode choke as an isolation transformer to analyze the open-loop response of a Peltz oscillator.

If your simulation software supports it, you can step through values of Rf and Ri to create closed loop gain settings that match the data sheet curves. Let’s use this circuit to test the Zout of the ...

Inductors and transformers serve key roles in switch-mode power supplies. Ensuring they perform as expected requires thorough in-circuit measurements performed under operating conditions. Here’s ...

Performing In-Circuit Inductor and Transformer Measurements in SMPS (.PDF Download) In switched-mode power supplies (SMPS), magnetic components, namely inductors and transformers, play critical roles.
