Abstract
Official abstract text for this publication.
A switching assembly includes a first terminal and a second terminal, and a contactor connected to the first terminal, where the contactor includes a relay switch and a coil. The switching assembly further includes a first switch connected to the second terminal, and a rectifier bridge connected in series between the contactor and the first switch. The switching assembly also includes a control unit configured to selectively apply a control signal to the coil to cause the relay switch to open or close based on a voltage measured at the first terminal or based on a voltage drop measured across the rectifier bridge.
