System for powering autonomous solar cookers by batteries

Scientific African, 2022
In this paper, we propose innovative autonomous solar cookers (hot plates and box ovens) supplied by batteries. The electrical energy is produced by photovoltaic panels (PV) and stored in a battery (24 V, 520 Ah). Hence, the cookers are powered through a

First‐order universal shadow filter designs with scaled time constants

International Journal of Circuit Theory and Applications, Volume 52, Issue 8, Page 4040-4053, August 2024.
First‐order generalized filter designs which simultaneously offer implementation of the low‐pass, high‐pass, and all‐pass filters basic functions with scaling of the associated time constant are presented in this work. These have been achieved thanks to the employment of the shadow filtering technique, which enables the utilization of a “hidden filter”

Complex‐order controller design examples and their implementation

International Journal of Circuit Theory and Applications, Volume 52, Issue 1, Page 473-482, January 2024.
A systematic method for approximating the complex‐order Laplacian operator by realizable integer‐order transfer functions is presented in this work. Both integrators and differentiators can be readily implemented by the same core. Discrete component and FPAA‐based implementations are provided for confirming the validity of the presented concept ...
