1. A current source power converter topology comprising:

  • an electric load;

    a stiff current source to power the electric load, wherein the stiff current source includesa voltage source,an inductor,a first switch, anda second switch, wherein each of the first and the second switches alternate between alternating open and closed positions and cooperate with the voltage source and further with the inductor to deliver a stiff but controllable current to the load;

    a driver associated with the electric load having power electronics disposed therewithin to drive the electric load; and

    at least one capacitor coupled to the load and to the power electronics to prevent transients from damaging the current source power converter.
