... One common technique used to enable soft-switching in resonant converters (e.g., series, parallel, series-parallel, LLC converters, etc.) is through frequency control. By modulating the converter switching frequency, variations in input voltage can be countered [13-15]. The cost to varying frequency ...

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.
