This AC power switch circuit senses the presence of AC current in one outlet of a multi-outlet power strip and switches power to the remaining outlet(s). It utilizes a current transformer, single ...

When choosing a switch to use in an electrical design project, there is a perception that it is possible to use any switch, provided its current rating is greater than the maximum load in the circuit.

Hotel rooms are often furnished with an interior key-holder near the main door which enables the ac power supply to everything in the room only when the key/keycard is hanged/inserted. The circuit ...

The key component of the dc power management system is the power supply that provides dc power for the associated system. The specific type of dc power management depends on its power input, which ...

Switch-mode power supplies (SMPS) continue to replace linear-regulator types in a host of applications. As the need for more efficient electronics accelerates and as a result of their size, weight, ...

This course introduces more advanced concepts of switched-mode converter circuits. Realization of the power semiconductors in inverters or in converters having bidirectional power flow is explained.
