  • Relay drive with power supply economizer
    Patent number: 11257645
    Abstract: Provided are embodiments for a circuit for a relay drive with a power supply economizer. The circuit includes a relay having a relay coil and a relay contact. The circuit also includes a power source to generate power for a coil drive voltage to operate the relay, and a controller configured to provide a command signal to operate the circuit in a plurality of modes. The circuit includes a first gate drive coupled to a first switch, wherein the first switch connects the relay coil to the circuit, and a second gate drive coupled to a second switch, wherein the second switch changes an effective resistance of a resistor network of the circuit to modify the coil drive voltage. Also provided are embodiments for a method for operating a circuit including relay drive with a power supply economizer.
