Power frequency converters take electrical input power at one frequency and voltage and provide electrical output power at a different frequency and at a different or equal voltage

Power supplies are devices that produce AC or DC power.

DC-DC converters accept DC input and provide regulated and/or isolated DC output in various applications including computer flash memory, telecommunications equipment, and process control systems

Power or line conditioners regulate, filter, and suppress noise in AC power for sensitive computer and other solid state equipment.

Voltage regulators are power converters that provide voltage control capabilities.

DC-DC converter chips provide a regulated DC voltage output from a different, unregulated input voltage.

Scan and video converters transform a digital computer image to a standard video signal for use with broadcasting or video devices such as televisions, monitors, or VCRs or vice versa
