Power supply technology is a basic technology that supports all types of electronic equipment. Switching power supplies, in particular, are characterized by small size, light weight and high efficiency and are the mainstream technology used in power supplies at present. In recent years, with the advent of an advanced information and communications-oriented society, trends toward personalization...

With electrical power supplies playing an important role in the operation of aircraft systems and sub-systems, flight and ground crews need health state awareness and prediction tools that accurately diagnose faults, predict failures, and project remaining life of these onboard power supplies. Among onboard power supplies, switch-mode power supplies are commonly used where their weight, size, a...

In this research, solar-drived integrated Hydrogen production (HP) using high-temperature steam electrolysis (HTSE) is thermodynamically evaluated. This system includes an organic Rankine cycle (ORC), Rankine cycle, Brayton cycle, solar tower, and High Temperature Steam Electrolysis (HTSE). Solar energy supplies thermal energy. This heat source is applied for generating power. This energy is us...

the methods which are used to analyze microstrip antennas, are divited into three categories: empirical methods, semi-empirical methods and full-wave analysis. empirical and semi-empirical methods are generally based on some fundamental simplifying assumptions about quality of surface current distribution and substrate thickness. thses simplificatioms cause low accuracy in field evaluation. ful...

A wireless ad hoc network typically refers to any set of wireless networks where all devices have equal status on a network and are free to associate with any other wireless ad hoc network devices in their range. As the nature of these networks, they commonly do not have external power supplies, and each node has a limited internal power source. In this paper, we put forward a new routing proto...
