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 ...
Some manufacturers of UPS units categorize their products in accordance with the number of power-related problems they address. [1] A UPS unit may also introduce problems with electric power quality. To prevent this, a UPS should be selected not only by capacity but also by the quality of power that is required by the equipment that is being ...
Buck–boost connections are used in several places such as uninterruptible power supply (UPS) units for computers and in the tanning bed industry. Buck–boost transformers can be used to power low voltage circuits including control, lighting circuits, or applications that require 12, 16, 24, 32 or 48 volts, consistent with the design's ...
An AC adapter or AC/DC adapter (also called a wall charger, power adapter, power brick, or wall wart) [1] is a type of external power supply, often enclosed in a case similar to an AC plug. [2] AC adapters deliver electric power to devices that lack internal components to draw voltage and power from mains power themselves.
Chopper circuits are used in multiple applications, including: Switched mode power supplies, including DC to DC converters.; Speed controllers for DC motors; Driving brushless DC torque motors or stepper motors in actuators

The charger provides a constant current, typically the maximum current that the charger is capable of producing. As a result of this current, the battery absorbs a charge and its voltage rises. The charger limits the maximum voltage to U max , a constant or temperature-dependent maximum, typically around 2.4 V per cell.
Push-pull converter (+12V → ±18V; 50W) as potted module. ① transformer; ② and ③ electrolytic capacitors vertical and horizontal mounted; ④ discrete circuit board in through-hole technology A push–pull converter is a type of DC-to-DC converter , a switching converter that uses a transformer to change the voltage of a DC power supply.
