Equation 36

so,

Equation 37

Each SPV1020 contributes to the output power providing Ioutx according to the irradiation of

its panel.

Furthermore, the desired VOUT is guaranteed if at least one of the 3 PV panels provides

enough power to turn on the related SPV1020.

B.2

SPV1020 series connection

This topology provides an output voltage that is the sum of the output voltages of each

SPV1020 connected in series. The following shows how the output power is impacted by the

topology.

Figure 29 shows a detail of the series connection topology:
