Certain specialized circuits can also be considered power converters, such as the flyback transformer subsystem powering a CRT, generating high voltage at approximately 15 kHz. Consumer electronics usually include an AC adapter (a type of power supply ) to convert mains-voltage AC current to low-voltage DC suitable for consumption by microchips.
A simple voltage dropper can be used to reduce the voltage for low-power devices; if more than 12V is required, or for high-powered devices, a switched-mode power supply is used. The output will usually be DC in the range 1.5–24 V. Power supplies that output either 100–120 V AC or 210–240 V AC are available; they are called inverters ...
A buck converter or step-down converter is a DC-to-DC converter which decreases voltage, while increasing current, from its input to its output . It is a class of switched-mode power supply . Switching converters (such as buck converters) provide much greater power efficiency as DC-to-DC converters than linear regulators , which are simpler ...
Stand-alone switched-mode power supply An adjustable switched-mode power supply for laboratory use. A switched-mode power supply (SMPS), also called switching-mode power supply, switch-mode power supply, switched power supply, or simply switcher, is an electronic power supply that incorporates a switching regulator to convert electrical power efficiently.
A digital TV converter box. A digital television adapter (DTA), commonly known as a converter box or decoder box, is a television tuner that receives a digital television (DTV) transmission, and converts the digital signal into an analog signal that can be received and displayed on an analog television set.

A frequency changer or frequency converter is an electronic or electromechanical device that converts alternating current of one frequency to alternating current of another frequency. The device may also change the voltage , but if it does, that is incidental to its principal purpose, since voltage conversion of alternating current is much ...
