DEFINITION

Classification: 323/351

Switched (e.g., switching regulators):

(under subclass 349) Subject matter wherein the system includes a single final control device which is operated in such a manner that it is either conductive or nonconductive.

(1) Note. The most common devices found herein are regulators wherein a switch such as a transistor is operated in a closed or open state. When closed an inductor typically stores energy, and when open, a flyback or catch diode will continue the flow of current or release of energy through the inductor to the load.
