Similar to magnetic core memory, or " cores ", magnetic amplifiers used small toroids of ferrite as a switching element.
12.
The exchange design concept lent itself to incremental upgrades, as the control elements could be replaced separately from the call switching elements.
13.
In medium to high loads, the DC resistance of buck converter switching elements tends to dominate the overall efficiency of the Buck Converter.
14.
Magnetic amplifiers were used extensively as the switching element in early switched-mode ( SMPS ) power supplies, as well as in lighting control.
15.
A flyback converter stores energy in the magnetic field in the inductor air gap during the time the converter switching element ( transistor ) is conducting.
16.
Relays and vacuum tubes ( thermionic tubes ) were commonly used as switching elements; a useful computer requires thousands or tens of thousands of switching devices.
17.
In power electronics applications, since the switching element is either fully on or fully off, its losses are low, and the circuit can provide high efficiency.
18.
He was a Bell Labs researcher known for his work in the 1930s and 1940s on the realization of Boolean logic digital circuits using electromechanical relays as the switching element.
19.
The various incoming channels of a common port are dispersed continuously onto a switching element which then directs and attenuates each of these channels independently to the N switch ports.
20.
When driving light loads, however, the effects of DC resistances are reduced and AC losses in the inductor, capacitor, and switching elements play a larger role in overall efficiency.
