Tailoring Model‐Based Systems Engineering for Sub‐100 g PlanarSats: A Power‐First View Stack

Systems Engineering, EarlyView.
ABSTRACT This paper addresses how to apply model‐based systems engineering (MBSE) to ultrasmall planar satellites under severe power and resource constraints. PlanarSats are sub‐100‐gram spacecraft built as single printed‐circuit boards where the same surface must host both electronics and solar cells, so power generation, geometry, and component ...

Proposed algorithm MPPT for Photovoltaic system

International Journal of Energetica, 2018
A proposed algorithm MPPT (Maximum Power Point Tracking) is proposed in this paper. When the insolation change rapidly, the P&O (Perturb and Observe) algorithm is used to adjust the operating point of the PV (Photovoltaic) array close to the MPP (Maximum Power Point) for fast tracking; also, the INC (Incremental Conductance) algorithm and the fuzzy

Simple Estimation and Application of the Differential Resistance of a Photovoltaic Module at its Maximum Power Point

IEEJ Transactions on Electrical and Electronic Engineering, EarlyView.
The modulating light irradiation method can estimate the target cell voltage in a working photovoltaic module without electrical contact. This method requires the differential resistances (DRs) of the target cell and module to quantitatively estimate the voltage.
