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

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

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

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

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 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

Electrical current sensors measure AC and/or DC current levels. They receive current inputs and provide outputs as analog voltage signals, analog current levels, switches, or audible signals

Charge pumps are circuits that generate higher voltages from low voltage inputs by using capacitors as storage elements. They are used in notebook computers and mobile phones.

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

Switch mode transformers (switching transformers) are used mainly in switching power supplies and DC-DC converters. They provide a storage element for transferring energy from input to output in discrete packets as required in switching power supplies, regulators and converters

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