Important aspects in the construction of the mechanical layout include the application conditions at which the components are put to use. These application conditions must be observed in the mechanical as well as the electrical design, the thermal design and the lifetime of the power modules based on [...]

03 June 2013
Overvoltage limitation between main terminals Measures to limit overvoltages between main terminals (collector-emitter voltage, DC link voltage) can be divided into passive snubber networks, active clamping, and dynamic gate control. Irrespective of the type of overvoltage limitation, the avalanche operation mode of a MOSFET can [...]
Power Module Basics
21 May 2013
Under normal circumstances, power electronics circuitry does not contain one single power semiconductor component but is composed of several components. When discrete devices are used, several of them, including their corresponding heat sinks, must be combined into one assembly to create a bundle of semiconductors that serve to [...]
Fault Current Detection and Reduction in Converter Circuits
08 May 2013
Errors in converter circuits may be detected at various points. The responses to detected errors, however, may be very different. The term fast protection is used if an error signal is detected in the switch or in close vicinity to the switch and the respective switch is turned [...]
650V Rapid Diode for Industrial Applications
02 May 2013
With the introduction of Rapid Diodes, Infineon Technologies enters the hyperfast fast high voltage silicon diode market. Based on ultrathin wafer technology, two families are released to cover different application requirements. Rapid 1 is used in low switching applications (up to 40 kHz) whilst the Rapid 2 is [...]
Fast IGBT based on TRENCHSTOPTM5 technology for industrial applications
29 April 2013
Historically, fast IGBTs have been proposed as the replacement of conventional or Superjunction MOSFETs due to higher power density. However, because of technology limitations, there are only limited areas where IGBTs can reach both commercial and technical advantages. The new TRENCHSTOPTM5 IGBT overcomes many of those technical limitations, [...]
Basic Considerations for Semiconductor Protection with Fuses
23 April 2013
Solid state devices have progressed through several generations of sophistication since their introduction in the 1940s. Fuse designs have changed to match solid state protection demands. The protection task seems simple - choose a fuse of correct voltage and ampere rating which will protect a solid state device [...]
