Appendix C

C.1

Power efficiency, MPPT efficiency and thermal analysis

The aim of this appendix is to show the efficiency and MPPT accuracy of the STEVAL-

ISV009V1.

The following equipment has been used:

Agilent Technologies E4360A Modular SAS Mainframe with module E4361A

Chroma 6314A DC ELECTRONIC LOAD Mainframe

LeCroy WaveRunner 6100 A.

Agilent 34401A digit Multimeter (as voltmeter)

Agilent U1242 digital Multimeter (as ammeter)

STEVAL-ISV009V1 (SPV1020 application board)

The following image shows the setup of the above environment.

Figure 30.

Measurement environment

The following figure (Figure 31) shows the power conversion when @VMPP =12 V, IMPP

ranges from 1 A to 8 A (step 1 A), and P ranges between 12 W and 96 W. The minimum

efficiency at P=96 W is 97 %.
