Abstract
A dynamic damping apparatus wherein the current source is critically damped during rise and fall of current but the DC flattop of the current is unaffected by the fluctuations of load voltage. Therefore the output impedance of the current source is low during rise and fall times, but high during the flattop. This increases current source regulation.
