Abstract
Power line current fed power supplies producing stable load currents and related methods are described. The power supplies may include a current transformer coupled to an inductive network. In some embodiments, the current transformer operates in saturation mode. In some embodiments, a substantially constant DC current is generated having a magnitude that remains substantially constant despite variations of the magnitude of AC current in the power line.
