I'm working in a simulation of a PV charge system and I'm using the DC - DC buck converter available in the examples of Simscape/Simulink. In my matlab, I can open the DC -DC buck converter with the command: elec_switching_power_supply. In this model, ther is a cyclic load component as it is shown in the picture that I add in this question. This component is a subsystem that has one controlled current source and a i_load goto. I don't understand the reasson why this component is in the simulation. Is this component simulating a real charge (I mean, a charge that can ask for current)? or there is another reason/function for this component to be in the simulation?
Please help me, thanks.
