Learn how to test a transformer: insulation resistance, TTR, winding resistance, polarity, continuity, and dielectric checks.

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 what ...

Analog Circuit Analysis can be difficult. Consider the circuit below. It includes a Series Resonant Circuit. With Ideal Impedances, the Series Impedance is equal to zero at the resonant frequency. A ...

This gate-drive transformer (GDT)circuit allows the drive signal to the MOSFET to range from 50% down to 0%, while still offering a fast turn-off that cannot be accomplished with a simple load ...
