Torque Control of Brushless Direct Current Motor Drives Using Single Current Sensor with High Reliability

Due to the simple structure, high torque density, low maintenance, and high efficiency, brushless direct current (BLDC) motors are widely used in automation and industrial applications. A control strategy based on single current sensor is proposed for a four-switch three-phase BLDC motor system to lower cost and improve reliability. The whole working process of the BLDC motor is divided into si...

Collective pulse-density modulation with neuromorphic single-electron circuits

We designed a neuromorphic single-electron oscillator network as an inhibitory neural network model that performs pulse-density modulation (PDM) [1]. The use of single-electron oscillator networks has been proposed for implementing functions of neural networks [2] and reaction-diffusion systems [3]. Single-electron circuits are being studied for use in next-generation LSI devices. We designed a...

Single Pulse Emittance Measurement Technique for Intense Relativistic Electron Beams

Single-shot femtosecond electron diffraction with laser-accelerated electrons: experimental demonstration of electron pulse compression.

We report the first experimental demonstration of longitudinal compression of laser-accelerated electron pulses. Accelerated by a femtosecond laser pulse with an intensity of 10¹⁸ W/cm², an electron pulse with an energy of around 350 keV and a relative momentum spread of about 10⁻² was compressed to a 500-fs pulse at a distance of about 50 cm from the electron source by using a magnetic pulse c...

Zinc-Nickel Binary Alloys Electrodeposition of Steel Using Pulse Current

Zinc-Nickel electrodeposits have been widely adopted for surface treatment of automobile steel sheet for high corrosion resistance. In this work the effect of pulse parameters on the Zn-Ni alloy electrodeposits was investigated. The hardness, thickness, corrosion resistance and composition of deposits thus produced were investigated. The surface topography of the deposits was also observed in S...
