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

A new method of injecting dc current into power inductors enables designers to avoid common pitfalls when measuring these devices, thus minimizing measurement errors. In power supplies, dc-dc ...

The demand for smaller, lighter, and more efficient AC/DC USB power delivery (PD) chargers is always a challenge for power-supply design engineers. Below 100 W, the quasi-resonant flyback is still the ...
