ABSTRACT:
A float stabilized constant current source uses a floated cylinder with a rotational signal output generator and two torque generators for applying a linear torque and an opposing current squared torque to the floated cylinder, respectively. The current squared torque is balanced against the linear torque by a servo system applying a current to the torque generators in series to create a point of zero net torque on the floated cylinder. The current is obtained from the signal generator representative of a cylinder rotation and is used as a stabilized constant output current, i.e., a precision constant current reference driving an electrical load.
