2. Voltage converter - Wikipedia

   en.wikipedia.org/wiki/Voltage_converter

   Such a device may be called a voltage converter, power converter, travel adapter, etc. Most single phase alternating-current electrical outlets in the world supply power at 210–240 V or at 100–120 V.

3. Electric power conversion - Wikipedia

   en.wikipedia.org/wiki/Electric_power_conversion

   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. Consumer voltage converters (also known as "travel converters") are used when traveling between countries that use ~120 V versus ~240 V AC mains power.

4. HVDC converter station - Wikipedia

   en.wikipedia.org/wiki/HVDC_converter_station

   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. The insulation ...

5. AC adapter - Wikipedia

   en.wikipedia.org/wiki/AC_adapter

   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.

6. AC-to-AC converter - Wikipedia

   en.wikipedia.org/wiki/AC-to-AC_converter

   An AC-AC converter with approximately sinusoidal input currents and bidirectional power flow can be realized by coupling a pulse-width modulation (PWM) rectifier and a PWM inverter to the DC-link. The DC-link quantity is then impressed by an energy storage element that is common to both stages, which is a capacitor C for the voltage DC-link or ...

7. Iptor Supply Chain Systems - Wikipedia

   Logo as International Business Systems. The company was founded as IBS in 1978 by Staffan Ahlberg and Gunnar Rylander. Both decided to form the company by turning the IT division of Ekonomisk Företagsledning into an independent company. Their first major project was to develop an order processing system for Alfa Laval subsidiaries. The company ...
