HX460 with External Pulse Width Modulated Drive
... GIGAVAC contactors require that coil current does not flow when the contacts open. Since PWM circuits require a freewheeling or fly back diode be placed across the coil this diode must be removed from the circuit when the contacts are opened. Figure 1 shows a typical circuit that can be used to t ...

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.
