1. A system for testing an energy generation device, the system comprising:

  • a. a load comprising a plurality of field effect transistors coupled in parallel, the load including a positive input terminal and a negative input terminal;

    b. a pair of electrical nodes to receive an energy generation device under test, with a first node coupled to the positive input terminal of the load, and a second node coupled to the negative input terminal of the load through a resistive element;

    c. a means for sensing the voltage drop across the resistive element;

    d. a difference amplifier to receive the sensed voltage drop across the resistive element and to provide an output which is a function of the sensed voltage drop;

    e. a control element coupled to the positive input terminal of the load, the control element further providing a first control signal to a first input to the load; and

    f. a feedback amplifier to receive the output of the difference amplifier and a second control signal from the control element, the feedback amplifier providing a second input to the load.
