“…Several works have treated the prediction of the amount of current harmonic that the ESLs inject into the power grid [60][61][62][63][64][65][66][67][68][69][70][71][72]. In [60] has been investigated the effect of the employing of many energy-saving lamps on the power grid in New Zeeland.…”

“…2019, 9, 152 4 of 32 been accurate, some particular CFLs under test have had to use some ad hoc adjustment to fit accurately with the measurements. Some researchers have worked out the behaviour of the CFL using an equivalent electrical circuit [65][66][67][68][69][70][71][72]. A common and general model is depicted in Figure 1, where the key circuit components are: a diode bridge that rectifies the main voltage, an AC equivalent resistor (Rac) and a DC smoothing electrolytic capacitor (C) supplying the downstream inverter that, in turn, feeds the fluorescent tube.…”

“…It is worth noting that in literature several procedures are developed to determine the parameters from the supply voltage and AC current measurements [68,69]. Other studies deal with the estimation of other non-linear loads using least-square algorithms [70][71][72]. In [70,71] the parameter estimation of single-phase rectifiers by analysing several non-linear sets of equations has been performed.…”

Energy-saving lamps are equipped with converters enabling high energy efficiency at the cost of injecting very distorted currents on the mains. The problem is more complex in the emerging smart-lighting scenario where these lamps are also used to perform additional tasks. Harmonics mitigation at the lamp level is expensive; consequently, an optimal lighting system design aiming at reducing both costs and current distortion of the whole lighting system is necessary. A tool able to emulate the current drawn from the lamps is necessary for optimal design. Such a tool has also to consider the fluctuations of the voltage on the mains that usually occur throughout the day. In this perspective, a parametric PSpice circuit is proposed and the netlist is reported in this work. Moreover, the simple procedure to be adopted for computing the parameters is also described. The validation has confirmed the ability of the proposed circuit in emulating the current drawn from various CFLs and LED lamps under different supplying voltage.
