DEFINITION

Classification: 327/531

Fluctuating or AC source with rectifier or filter:

(under subclass 530) Subject matter wherein the power supply is converted from an alternating or fluctuating input voltage or current to a direct current or voltage via a rectifier circuit or is smoothed or integrated by a filter circuit.

(1) Note. The power supply may contain both AC and DC components, and the DC component is received from the output by coupling to a rectifier or a filter circuit.

330, for amplitude limiting systems with a rectifier.

552, for unwanted component eliminating systems with a filter.
