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 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

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

IC voltage regulators are three-terminal devices that provide a constant DC output voltage that is independent of the input voltage, output load current, and temperature. IC voltage regulators are used in power supplies that hold their output voltage constant over a wide range of load variations

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

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

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 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

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

DC to AC inverters are used for converting direct current (DC) into alternating current (AC). They are also known as DC to AC converters

AC-DC adapters accept AC input voltage directly from a wall outlet, and output DC voltage

DC motors are most commonly used in variable speed and torque applications. They include brushless and gear motors, as well as servomotors

Power transformers convert power-level voltages from one level or phase configuration to another.  They can include features for electrical isolation, power distribution, and control and instrumentation applications

Power electronics are solid state devices or transistors capable of modulating or converting electrical power.

Gearmotors consist of an AC or DC motor with an integral gearbox or gear head that steps delivered speed up or down
