DC-to-DC converter - Wikipedia to DC converters are used in portable electronic devices such as cellular phones and laptop computers, which are supplied with power from batteries primarily. Such electronic devices often contain several sub-circuits, each with its own voltage level requirement different from that supplied by the battery or an external supply (sometimes higher or lower than the supply voltage).

Transformers | CESI transformers are key components in power production, transmission and distribution, interconnecting systems that have different rated voltages, from power plants to final users. KEMA LABS tests power and distribution transformers up to the highest power and voltage ratings in use today. We test transformers to standards such as IEC 60076 (oil-filled), IEC 60076-11 (cast resin) and ANSI ...
