Due to fact that the power electronic converters operate in switch mode (the conversion of energy is done by means of blocking and unblocking of solid state switches of the device), the generation of the higher current harmonics is inevitable. However, not only such devices are sources of harmonics ...

Transformer types
A variety of types of electrical transformer are made for different purposes. Despite their design differences, the various types employ the same basic principle as discovered in 1831 by Michael Faraday, and share several key functional parts.
