in this paper, plug-in fuel cell electric vehicle (pfcev) is considered with dual power sources including fuel cell (fc) and battery energy storage. in order to respond to a transient power demand, usually supercapacitor energy storage device is combined with fuel cell to create a hybrid system with high energy density of fuel cell and the high power density of battery. in order to simulate the...

Applied diagnosis based on audible sound enrichment that realize the measurement and control for high efficient energy systems 7. Overview of the Results of the Collaborative Research: In recent years, a mechanism that controls the system intelligently by using information of the various data shared on the system network has been practiced. New power grid systems (smart grid), and electric vehi...

Yuichi Baba Atsushi Hiratsuka Eiji Sasaki Osamu Yamamoto Masakazu Miyamoto OVERVIEW: Railways must operate safely and in accordance with their timetables, and the signalling systems responsible for ensuring safety have been progressively improved in response to demand for greater safety, reliability, and efficiency. Drawing on technology built up through its experience with signals and safety s...

Electric power steering systems are a quite common equipment of modern vehicles. They are based on torque controlled electromechanical actuators assisting the driver in moving the steering wheel. These systems must generate low torque fluctuations and mechanical vibrations, while featuring a low cost and a simple and rugged control system. In order to comply with these requirements an electrome...

Applying a unique 3-channel RS-485 transceiver displaying many unusual features increases reliability and fault-detection in motor-control applications. Designed specifically for motor shaft encoder applications, the MAX3097 and MAX3098 feature three differential channels to handle optical encoder data, ±15kV ESD protection, increased common mode rejection to -10 and +13.2V, three separate faul...

Solid-state nanopores have emerged as a versatile tool for the characterization of single biomolecules such as nucleic acids and proteins. However, the creation of a nanopore in a thin insulating membrane remains challenging. Fabrication methods involving specialized focused electron beam systems can produce well-defined nanopores, but yield of reliable and low-noise nanopores in commercially a...

Power distribution system in the country is characterized by high power losses, poor reliability of supply, frequent equipment burnouts etc. The traditional approach in electric power generation is to have centralized plants distributing electricity through an extensive transmission & distribution network. Distribution generation (dg) provides electric power at a site closer to the customer, el...
