  • DC current controller for hydroset battery electrode electroformation
    Patent number: 4656411
    Abstract: A closed loop regulating system suitable for battery plate formation is provided. The circuit incorporates MOS FET and provides compensation for resistance changes that occur in MOS FET devices due to temperature changes. The regulating system also has means to precisely compensate for substantial impedance changes that occur over long time periods of an electroforming cycle for loads of various sizes.
