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

Orion Fans’ series of smart, thermally controlled ac and dc fans deliver high airflow to help prevent premature LED component failure in solid-state lighting due to excessive heat.

Power relays are specifically designed to handle either AC or DC. It’s important to know the fundamental differences between them before building them into a system.

By manipulating the switching frequency and turns ratios of the transformer, the circuit can have an arbitrary output voltage. In this case, it is designed to take 220V AC and convert it to 8V DC.

Thomas Edison favored DC circuits, but Nikola Tesla thought AC circuits were the way to go. Clearly Tesla won that argument. Let’s see why!
