Drivetrain - Doubly-fed converter

The power circuit

The power circuit handles incoming power from the generator and outgoing power to the grid. Managing high power, typical components are air circuit breakers and large contactors. Another key function is over-voltage protection (OVR, SPD).

Modern drivetrains normally include a converter and one the main solutions is called Doubly-fed. In addition to the main circuit, the converter itself has several functions that need low voltage components.

Switch and disconnect

Protection and safety

Metering, monitoring and signaling

Enclosure, connection and installation equipments
