  • Constant current supply for a varying resistance
    Patent number: 4748551
    Abstract: The circuit includes a low-impedance source of a symmetrical alternating voltage wave composed of a fundamental and odd harmonics, and further includes a transmission line having a delay equal to an odd number of quarter cycles of the fundamental, having one end connected to the low-impedance source and the other end connected to the load. The circuit should be useful wherever it is desired to maintain the flow of current constant in spite of variations in the load resistance.
