Use of the vanadium-compensated semi-insulating (VCSI) 4H-SiC photoconductive semiconductor switch (PCSS) for generation an ultra-wideband (UWB) microwave with MHz tunable re-frequency is demonstrated. To evaluate impact device architectures on performance, a 4H-SiC-based was manufactured and evaluated using laser cluster driver configurable optical pulse re-frequency. The 1.5 mm-thick PCSS fou...

The paper presents the development of a megavolt-class SF6-insulated radial switch. switch is used as crowbar in MV Tesla-type generator to produce pulsed electric fields very large volumes, for proof-of-concept experimentation novel non-invasive food processing technology. main features include: (1) Using SF6 gas insulation gas; (2) breakdown channel along direction, rather than axial; (3) com...

Two of the main challenges recent electric vehicles (EVs) are charging time and high initial cost. To solve problem associated with long time, car manufacturers moving from 400 V battery EV (BEV) to 800 BEV, which enables utilization multi-level converters in applications. This paper presents a power conversion system consisting Vienna rectifier two/three level hybrid inverter as machine-side d...

As we witness a global change occurring with the advent of e-scooters (electric scooters), it is clear that adequate measures need to be taken for implementation this means transport. Bearing in mind user should focus proposed measures, aim paper encompasses analysis e-scooter users’ travel patterns, as well standard scooter willingness switch different hypothetical scenarios, and determination...

Background: Cellular biomechanics can be manipulated by strong electric fields, manifested by the field-induced membrane deformation and migration (galvanotaxis), which significantly impacts normal cellular physiology. Artificial giant vesicles that mimic the phospholipid bilayer of the cell membrane have been used to investigate the membrane biomechanics subjected to electric fields. Under a s...

This article presents an accurate method to determine the mandatory rotor position control a permanent magnet synchronous machine from misplaced Hall-effect switch sensors. The main feature of this technique is estimated speed two consecutive edge transitions in same phase dodge inaccurate information. Besides, when new electrical cycle starts, gradual compensation algorithm corrects initial es...

many studies have been done on hybrid vehicles in the past few years. the full hybrid vehicles need a large number of batteries creating up to 300 (v) to meet the required voltage of electric motor. the size and weight of the batteries cause some problems. this research investigates the mild hybrid vehicle. this vehicle includes a small electric motor and a high power internal combustion engine...

Trucks account for one-fifth of transport sector emissions in Europe. To decarbonise, heavy-duty road freight must switch to zero-emission vehicles quickly. This report examines whether battery electric vehicles, systems and hydrogen fuel cell could compete with diesel-driven vehicles. It looks at the total cost ownership across nine different vehicle-size segments The gives six recommendations...
