A shortage of transformers is causing delays to power projects everywhere, holding trillion-dollar industries hostage—and ...

This FAQ will look at the advantages and attributes of three-phase AC, also called multiphase or polyphase AC.

A power tip that discusses how to address highly integrated USB PD charger design constraints with a self-biasing circuit.

Transformers will only work with an alternating current (ac) input. This transformer steps up the voltage by reducing the current. Step-down transformers are used to decrease or 'step down' voltages.
