  • Noise Filter Design For Imbalanced Currents In Downhole Applications
    Publication number: 20240250655
    Abstract: An electromagnetic interference (EMI) filter disposed in a downhole tool. The EMI filter may include at least one common mode choke. The at least one common mode choke may include a high permeability magnetic core and three coils wound around the high permeability magnetic core. The three coils may include an input and an output. The EMI filter may further include a power supply connected to two coils of the three coils and a common ground connected to a third coil of the three coils.

  • SYNCHRONIZING DOWNHOLE SUBS
    Publication number: 20170315263
    Abstract: Systems for synchronizing downhole subs are disclosed. Some system embodiments may include a first downhole sub including a clock signal generator configured to generate an unmodified clock signal. The first downhole sub may also include a modification circuit configured to modify the clock signal. The system may also include a second downhole sub comprising a phase-locked loop circuit configured to receive as input the modified clock signal and output a second clock signal synchronous with the unmodified clock signal.
