Power supplies are devices that produce AC or DC power.  This grouping includes current sources, DC power supplies, AC-DC adapters, DC-DC converters, AC power sources, and DC-AC inverters

Medical power supplies produce conditioned outputs for medical devices, instruments, and equipment.

DC power supplies accept an input power and output the desired form of DC power. Common types of DC power supplies include linear power supplies, switching power supplies, DC-DC converters, and silicon controlled rectifier (SCR) type power supplies

DC motor drives act as the interface and power supply between a motion controller and a DC motor

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

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 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

DC to AC converter chips transfer a DC input into AC power by using switching, inversion, or other technology

SCR power supplies use silicon controlled rectifier (SCR) topology to provide well-regulated voltage and current output

AC to DC converter chips transfer an AC input into DC power using switching (MOSFET, IGBT) or rectification (diodes, Schottky diodes

Silicon controlled rectifier (SCR) power controllers precisely regulate output power to resistive heating loads such as industrial furnaces and ovens. They generally operate on either zero-crossing or phase angle control

Selective catalytic reduction (SCR) systems inject ammonia into boiler flue gas and pass it through a catalyst bed where the nitrogen oxide gas (NOx) and ammonia react to form nitrogen and water vapor

Silicon controlled rectifiers (SCR) are four-layer (PNPN) thyristors with three terminals: an input control terminal (gate), an output terminal (anode), and a terminal common to both the input and output (cathode). SCRs are used mainly with high voltages and currents, often to control alternating current (AC) where the change of sign causes the device to switch off automatically

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

Analog-to-digital converter (ADC) chips transform information from analog to digital form
