Posted on 01 January 2007

      Isolation Amplifiers with Shunt Resistors vs. Hall-Effect Devices The current sensor is an essential component in a motor control system. Recent progresses in sensor technology have improved the accuracy and reliability of sensors, while reducing their cost. Many sensors are now available that integrate a sensor and signalconditioning circuitry into a single [...]

Coreless Transformer Provides Innovative Features

Posted on 01 January 2007

      The expansion of the EiceDRIVER-family Coreless transformer technology was introduced in the market by Infineon Technologies in 2003 [1, 2] as a core technology for IGBT gate drive ICs. Coreless transformer technology may be either used to replace half-bridge drivers, which use level shifters, or to replace optocouplers. By Wolfgang Frank, Bernhard [...]

Loop Stability of Switch Mode Power Supplies

Posted on 01 January 2007

      A practical measurement approach with the use of a network analyser Knowing the stability criteria’s of a switching power supply and measuring its close loop gain and phase over a certain frequency range helps the designer to understand potential risks of instability of the analysed design. By Werner Berns, Application Design Centre [...]
