By implementing coupled-inductor (CI) and built-in transformer (BIT) together with a switched capacitor (SC) voltage multiplier cell (VMC), higher degree of flexibility is achieved for improvement step-up in comparison those which only one these magnetic devices utilised. Furthermore, the imposed across ...

Pollution is <span>one of the most hazard facing in world. Day by day pollutions has been increased society due to population growth, industries, constructions, and transportation. As per world health organization (WHO) survey, 45% air pollution transportation because they lay on internal combustion engine (ICE) based engines. To avoid carbon footprints, green should be encouraged for fur...

This project presents a novel battery-less wireless sensor that can be embedded in the road and used to measure traffic flow rate, speed and approximate vehicle weight. Compared to existing inductive loop based traffic sensors, the new sensor is expected to provide increased reliability, easy installation and low maintenance costs. The sensor uses power only for wireless transmission and has ZE...

This paper proposes an optimized step-up power converter using a quadratic sawtooth waveform generator for silicon photomultiplier (SiPM) used as radiation sensor mobile dosimeters. Although our uses the topology of switched inductor boost in voltage mode, it achieves fast transient performance thanks to proposed generator, which can increase loop bandwidth. As result, stably regulate bias SiPM...
