  The compact, two-row connection solution for drive controllers – Compliance with existing standards despite extremely compact installation space. The current trend towards smaller and smaller drive controllers with increasingly high power is being addressed by Weidmüller in the form of an innovative connection solution - the very compact double-level OMNIMATE Power SVD 7.62HP male [...]

  With the increase of renewable energy systems the g rid requirements regarding compensation of energy overload and energy lack situations rises. Different technologies for energy storage systems are used in the market like battery storage and flywheel solutions. SEMIKRON already has a wide ready-to-use portfolio of different stacks for these kind of applications from [...]

  Contributes to greater miniaturization, stable operation, and reduced customer design load in the automotive and industrial markets ROHM has recently announced the development of the BD51180TL, a step-down DC/DC converter featuring the lowest minimum ON time in the industry, making it ideal for high-power applications such as industrial equipment and automotive systems. In recent [...]

  Contributes to improved performance and longer battery life in portables such as smartphones and tablets ROHM has recently announced the availability of a compact, high-efficiency, high power synchronous boost DC/DC converter IC optimized for single-cell battery applications. Many of today’s portable devices (i.e. smartphones and tablets) are driven by single-cell li-ion batteries that deliver [...]

  ROHM has recently announced the development of a 1200V/300A full SiC power module designed for inverters and converters in solar power conditioners and industrial equipment. The 300A rated current makes the BSM300D12P2E001 suitable for high power applications such as large-capacity power supplies for industrial equipment. In addition, 77% lower switching loss vs. conventional IGBT [...]

  Flux gate sensor The flux gate principle is familiar from the flux-gate magnetometers. These were developed during the second world war and used by low flying aircraft to detect submarines. These days fluxgate sensors are used in gyro compasses and in lab equipment to measure remanent magnetism for example. The flux-gate magnetometer can measure [...]

  Based on a recent publication (in Chinese) released on the 16th of December 2013, it seems that the Chinese government has introduced to its tariff policies a 3% customs duty for importing power electronics modules into China. There is a general tariff of 10% applied, e.g. on drivers, and a temporary, or provisional, tariff [...]

  Almost every machine or industrial process contains one or more rotating shafts. It is therefore important in most instrumentation systems or control systems to be able to measure the exact shaft angle of a mechanical shaft. This angular data can be used to control position, speed or acceleration of a mechanism. Standard shaft angle [...]

              The electric supercar E-RA (Electric RaceAbout) was able to improve the lap time on the Nordschleife track by an impressive 20 seconds to 8:23.56. The electric vehicle is powered by VISEDO PowerMASTER™ inverters and motors based on VISEDO PowerDRUM™ technology. One of the key improvements from the last [...]

              'Focus on our strengths' is a motto of our times. It’s likely to be heard in the financial results of a giant multinational, or seen in the business plan of the newest startup. It leads in different directions depending on just what those strengths are. In power electronics, [...]
