Solar array emulator and MPPT tester for the Masat-1 mission

This paper shows testing equipment specially developed for electrical power system of pico-satellites. The equipment enables to verify the correct functioning of maximal power point tracker circuits emulating the power input of the solar cell arrays and the determination of the power balance. The development of the device was largely based on the design of Masat-1 picosatellite. The paper shows the properties of the solar cell arrays to be emulated, the concrete realization of the tester, and its functioning illustrated by measurement results.
