... Comparison of an Isolated bidirectional Dc-Dc converter with and without a Flyback Snubber power by the flyback snubber is typically around 5% of the full-load power for low-voltage applications. With the flyback snubber, the energy absorbed in CC will not flow through switches M1–M4 , which can re ...

HIS – Highly Integrated Switchgear up to 550 kV, 63 kA
... The pressurized gas inside the enclosure in combination with the film insulation provides insulation against high voltage. The high-voltage connection to the switchgear is established via the primary conductor, which is supported by a gastight bushing. The secondary connections are routed via a gast ...

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.
