Powering LED Arrays in Backlight Applications

Posted on 01 August 2006

       32 LEDs are driven from a 12V supply LEDs are becoming an increasingly popular backlighting option for all types of LCD displays, large and small, as more efficient and more cost-effective white LEDs become available on the market. By David Sorlien, Applications Engineer, Intersil   Advantages of LED backlighting include low cost, [...]

HEV Converters Based on PCC Technology

Posted on 01 August 2006

      Innovative Miniaturized System Solutions The solution can be realized on the basis of the innovative and integration-friendly Power Capacitor Chip (PCC) technology. This technology was mainly developed for the DC link capacitor, one of the key components of an HEV converter. By Harald Vetter, Epcos AG, PM Power Electronic Capacitors   The [...]

Reduced Switching Losses and Higher Operating Temperature

Posted on 01 August 2006

      IGBT4 chip generation enables efficient high current power modules With the 1200V IGBT4 chips Infineon introduced a new generation of IGBTs. The goal of this innovative IGBT development was to reduce the saturation voltage and simultaneously decreasing the switching losses to improve the trade-off between static and dynamic losses. By Marco Baessler, [...]

IC Tailored for Battery Charging

Posted on 01 August 2006

       Single Li-Ion/Polymer cells are in focus Single cell Li-Ion/Polymer batteries are the preferred voltage source for various portable equipments such as PDAs, cellular phones and digital still cameras (DSCs) because they offer the highest energy density, the lowest self discharge rate and the thinnest profile. By Merisio Massiniliano, STMicroelectronics   The biggest [...]

Next Generation 3.3kV IGBT Module

Posted on 01 August 2006

       HVIGBT modules will provide lower power losses High power applications require high voltage IGBT (HVIGBT) modules operating with low power losses and high reliability. However, these specifications are often in a reciprocal relationship to each other. By S. Iura, A. Narazaki, M. Inoue and S. Fujita, Mitsubishi Electric Corp. Power Device Works [...]
