Abstract: A mathematical model for nonlinear loads, that contains, in its design, a switching power supply is presented. The model was tested in home appliances operating in a Direct Current Home Nanogrid (DCHN). Compact Fluorescent Lamps (CFLs) and LED lamps were used as nonlinear loads to study, through the model, the experimental results in the profile of ripple in voltage and current of the lamps. The profile of ripples, due to the home appliances, could be explained by the model, even in the simultaneous operation of two loads. Additionally, the effect of decreasing the ripple amplitude when an induction stove in standby mode was incorporated with the DCHN was analyzed.
