The high-side linear current source includes a voltage source and a feedback loop in which an operational amplifier controls the generation of source current in response to a reference signal received from a controller and a feedback signal received via the feedback loop. The output circuit produces an output current, and includes one or more components with configurable electrical parameters which, in combination, simulate electrical characteristics of a PV panel. In response to connection of a load of an IV curve tracer, the PV panel simulator produces an output current produced at a magnitude that settles from an initial state to approximately a steady state within a settling time period. The settling time period precedes a measurement time period during which the IV curve tracer measures the output current and voltage in the steady state.
A control system controls an inductor-inductor-capacitor (LLC) converter according to a switching method that tunes the output power of the LLC converter based on the required power to be supplied to an output load coupled to the LLC converter. The tuning of the output power is based in part on changing the duty cycle of a switching module. In addition, the output power is adjustable by changing a frequency of switching (e.g., a pulse width of the switching module output). The control system is capable of adjusting amplitude and changing rising slope of a current supplied to the output load by changing the duty cycle and pulse width of the switching. A piece-wise linear control method is achieved by controlling the duty cycle and pulse width differently when the input voltage is lower than a crossover voltage than when the input voltage is higher than the crossover voltage.
