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 single-phase, three-winding converter transformer. The converter transformers step up the voltage of the AC supply network. Using a star-to-delta or " wye-delta " connection of the transformer windings, the converter can operate with 12 pulses for each cycle in the AC supply, which eliminates numerous harmonic current components.

Valve voltage and current for inverter operation with γ=20° and μ=20° The DC output voltage of the converter steadily becomes less positive as the firing angle is increased: firing angles of up to 90° correspond to rectification and result in positive DC voltages, while firing angles above 90° correspond to inversion and result in ...

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.
A power inverter, inverter, or invertor is a power electronic device or circuitry that changes direct current (DC) to alternating current (AC). [1] The resulting AC frequency obtained depends on the particular device employed. Inverters do the opposite of rectifiers which were originally large electromechanical devices converting AC to DC. [2]
A "transformer bank", widely used in North America: three single-phase transformers connected to make a 3-phase transformer. The low-voltage secondary windings are attached to three or four terminals on the transformer's side. In North American residences and small businesses, the secondary is often the split-phase 120/240-volt system. The 240 ...
