Averaged large-signal model of a DC-DC isolated forward resonant reset converter for a solar cell battery charger using internet of things: implementation

Abstract

In this study, an analysis and modeling circuit for controlling battery charge solar cells based on data management through internet of things (IoT) is presented. For this proposed, a DC-DC forward resonant reset converter is employed and can be charged at a constant current and constant voltage. Data management of various parameters using IoT technology is provided, via which notifications can be sent to an external application. The proposed converter can give an output voltage of 14.4 VDC for a voltage range including between 9 and 18 VDC, using an isolated transformer and a halfwave rectifier circuit. The main switch of the forward resonant reset converter can operate under a zero-turn-on condition. This approach has the benefit of utilizing a leaking inductance. Llkp and resonant capacitor Cr to reset the remaining flux saturation on the high-frequency transformer. A simulation model prototype was created and tested at a set switching frequency of 50 kHz, 14.4 VDC constant output voltage, and output power of approximately 29 W. An efficiency of 96% at maximum full load can be reached. The proposed analysis techniques and mathematical model were verified via simulation and experimental results, and the obtained results are in agreement with the theoretical analysis.

Experimental investigation of bidirectional series resonant DC-DC converter in different operating modes

“…Therefore, hybrid power generation systems become more common [7]- [11]. To increase the system efficiency, battery storage technologies are implemented [12]. In such a way, during an energy production peak, the surplus of energy could be stored, and when the generation becomes lower than the consumption this energy could be reverse feeding into the main supply.…”

A regulatory power split strategy for energy management with battery and ultracapacitor

“…Numerous power control strategies are available in the literature [26]- [28] for hybrid energy structures. Controllers also rely on the internet of things [29], [30] for the data flow in PV based systems or AI as in [31] for multi agent systems utilising not only solar and wind but also SC, battery and generator, and utilising piezo electric energy harvesting [32]. HESS control strategies can also address the power quality issues [33] in the system.…”
