  • Enhanced over voltage protection of a downhole system
    Patent number: 11527886
    Abstract: A power system a method for enhanced voltage protection. The system may comprise a surface high voltage power supply, a voltage controller connected to the surface high voltage power supply that sends commands to the surface high voltage power supply to control an output voltage of the surface high voltage power supply, one or more power cables attached to the surface high voltage power supply, a downhole tool connected to the one or more power cables at an end opposite of the surface high voltage power supply, and a dynamic clamp circuit connected to the surface high voltage power supply. A method may comprise creating a setpoint with a dynamic clamp circuit based at least in part on the command, activating the dynamic clamp circuit when the output voltage is higher than the setpoint, and absorbing excess energy from the high voltage power supply with the dynamic clamp circuit.
    Type: Grant
