In such cases, voltage converters need only be specified to convert any voltage within one range, to a voltage within the other, rather than separate converters being needed for all possible pairs of nominal voltages (110–220, 117–220, 110–230, etc.)
For this reason, an HVDC converter using IGBTs is usually referred to as a voltage-source converter (or voltage-sourced converter [26]). The additional controllability gives many advantages, notably the ability to switch the IGBTs on and off many times per cycle in order to improve the harmonic performance, and the fact that (being self ...
Consumer voltage converters (also known as "travel converters") are used when traveling between countries that use ~120 V versus ~240 V AC mains power. (There are also consumer "adapters" which merely form an electrical connection between two differently shaped AC power plugs and sockets , but these change neither voltage nor frequency.)

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 ...
12 V DC, for smaller consumer and commercial inverters that typically run from a rechargeable 12 V lead acid battery or automotive electrical outlet. [3] 24, 36, and 48 V DC, which are common standards for home energy systems. 200 to 400 V DC, when power is from photovoltaic solar panels.
DIY was originally founded by Vimeo co-founder Zach Klein, [2] Isaiah Saxon, Andrew Sliwinski, and Daren Rabinovitch in May 2012. [3] [4] The company launched a second online children's educational platform in 2016 called JAM.com, [5] [6] which was subscription-based and more focused on a course structure for learning versus DIY's free and badge-based skill building structure.
Fig 1: Classification of three-phase AC-AC converter circuits. [1] Referring to Fig 1, AC-AC converters can be categorized as follows: Indirect AC-AC (or AC/DC-AC) converters (i.e., with rectifier, DC link and inverter), [2] such as those used in variable frequency drives; Cycloconverters; Hybrid matrix converters; Matrix converters (MC)
