Large scale requirement engineering needs automated precise and efficient capability modeling and analyzing methods formally to interoperate with the evolving and goal driven requirements. The proposed capability driven requirement engineering framework presents a two-layer framework for the automation of requirements engineering. In the first layer, a meta-model is proposed to define a fault-free model instantiating […]
An innovative Synchronous Buck Converter (SBC) with a wide input voltage range is presented in this article for use in Electric Vehicle (EV) applications. The disadvantages of higher losses in an Asynchronous Buck Converter (ABC) are intended to be addressed by the Synchronous Buck Converter. Fewer losses occur in the circuit when MOSFET (or any […]
Sulfur hexafluoride (SF6) is extensively utilised as an essential insulating material in high-voltage industries owing to its outstanding electrical characteristics. However, the use of SF6 gas faces two significant challenges: its substantial impact on global warming and the high toxicity of its breakdown byproducts.

A double-coupled isolated inductor-based high step-down DC-DC converter is proposed in this work. This converter employs two windings on the secondary section of every coupled coil within a single core which enhances the utilization factor of the core. As the primary section voltage of the second coil is reduced, the leakage inductance and turn ratio […]
Jet engines consume a lot of power at start time which makes necessary to use a ground power supply unit (GPU). The GPU must provide the aircraft’s demanded power at the start point only. One of the most important factors in supplying the required power for jet engines is to provide the necessary quality for […]
