System setup

The system setup that can be used for the evaluation of the SPV1050 device is shown in

Figure 4:

Figure 4. Measurement system setup

The supply system emulates the I-V characteristic of a PV panel and it is composed by

a power supply VGEN, to determine VOC, and a resistor RIN, to determine IMP and VMP.

Considering the typical electrical parameters of a PV panel (VOC, VMP, IMP, ISC), the supply

system has to be set as following:



VGEN = VOC



RIN = (VOC - VMP)/IMP

At the output stage a real battery can be connected to the BATT pin. The battery can be

emulated by a power supply with a resistor (RBATT) in series.
