In industrial and process control, it is often necessary to accurately control the temperature of a process. You control most heating elements using the “bang-bang” method—turning the power to them on ...

Power control using the linear region of an active device, such as a MOSFET, is not an efficient option. However if the range of power control is restricted to the lower or upper end of the range, ...

This design describes a simple, cost-effective solution for an ac power controller using PC-compatible conduction-angle control. A solid-state relay (SSR) is activated through a pulse-width-modulated ...

The Mysa Smart Thermostat for AC is an attractively designed, easy-to-use, reliable device for controlling a standalone air conditioner. Mysa’s new controller looks very much like a smaller version of ...

Dealing with power density through modularity. The value of a fully digital power supply relates to the data. Interpreting the data: The role of the power supply’s user interface. A fully digital and ...

The 19th century battle between Nikolai Tesla’s alternating current (AC) and Thomas Edison’s direct current (DC) technologies had an undisputed winner. The vast majority of the world’s transmission ...
