Technology for Wind Turbine Inverter with Increased Reliability

Posted on 01 January 2009

      The continuously increasing part of renewable energy in the generation of electricity requires a huge quantity of power semiconductors. Among the most cost effective renewable energy sources are the wind power plants. Frequency converters constitute an important part and facilitate the grid compliant power supply. Power semiconductors meet the requirements of this [...]

Digital Drivers with Exceptional Protection

Posted on 01 January 2009

      Digital gate drivers for high power IGBT modules up to 6500V The intelligent digital IPS-drivers decrease the switching losses and offer excellent protection for the IGBT modules. The drivers may be easily adapted to specific applications by changing the software. By Pavel Kviz, Robert Hemmer and Marita Wendt, InPower Systems GmbH   [...]

Brain Cells: Intelligent Efficiency for Solar Systems

Posted on 01 January 2009

      Adding a little intelligence to solar power can increase the efficiency, and the lifetime Techniques for a modular battery system for solar applications range from the simple use of a rectifier diode, to the brute-force approach of using Maximum Power-Point (MPP) converters. Whilst both techniques can achieve the objective of storing power [...]

Aero Trends

Posted on 01 January 2009

      Future electrical power challenges and solutions within the aerospace industry The aerospace industry always plans several years ahead. It has to. For example, now that Airbus’ and Boeing’s most recent strategies for multi-aisle long-haul aircraft have all but played out, thoughts are now turning to next generation short-haul, single-aisle aircraft – aircraft [...]

Benefits of Design Software

Posted on 01 January 2009

      Boundary Element Method can reduce computational and modeling times The key purpose of design software is quite simply to make existing products work better for less, and to allow designers to test completely new ideas without the often prohibitive cost of building, testing and making mistakes. To build almost anything we start [...]
