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...

Reliability Issues in Power MOSFETs

Process influences on NBTI as observed on 30nm-GOX trench MOSFETs of two recent power technologies are presented. Both front end of line (FEOL) und backend of line (BEOL) processes are shown to have major effects on the interface quality. A p-channel device serves as demonstrator that nitrogen, introduced into the MOS system during a long-time, high-temperature diffusion step in FEOL processing...

Reliability Issues for Linear Colliders*

To deliver a high integrated luminosity over several years of operation, a linear collider must not only meet its energy and luminosity performance goals, but also have a very high hardware availability and operating efficiency. The first challenge is the size and complexity of the facility. If the typical reliability of existing High Energy Physics accelerators is simply scaled to the size of ...

Clopidogrel Resistance: Current Issues

Antiplatelet agents are mainly used in the prevention and management of atherothrombotic complications. Dual antiplatelet therapy, combining aspirin and clopidogrel, is the standard care for patients having acute coronary syndromes or undergoing percutaneous coronary intervention according to the current ACC/AHA and ESC guidelines. But in spite of administration of dual antiplatelet therapy, so...
