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 ...

Transformers have been the backbone of power grids for over a century, but today’s demands for renewable energy, electric vehicles, and smarter grids are exposing their limits. Enter solid-state ...

If you’d like to build a Jacob’s ladder, an ignition system for a flamethrower, or for some ungodly reason you need 15 kilovolts for a prop replica or cosplay build, this one is for you. It’s an easy ...

step-down transformers decrease the voltage. The transformer in the diagram above is a step-down transformer – there are fewer turns on the secondary coil than on the primary coil. Type of transformer ...

The problem of transformer core saturation can lead to the failure of bridge and push-pull topologies. This was successfully solved during a research and development project for a DC/AC inverter that ...
