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 [...]

Loss Reduction in Power Electronics Switches by Soft Switching

19 April 2013

              Soft switching is a possible way of reducing losses in power electronic switches. The expression "soft switching" actually refers to the operation of power electronic switches as zero-voltage switches (ZVS) or zero-current switches (ZCS). The many different converter circuits that working according to these principles are generally assigned [...]

Sintering Technology

17 April 2013

              Sintering combines two fine grained ceramic or metallic materials, usually under high pressure, at temperatures below the melting point of both materials. At a temperature of around 250°C, fine silver powder is sintered under high pressure to form a low-porous silver bond layer between the parts to be [...]

Driver Units for Thyristors

15 April 2013

              The link between the electronic control components of a converter and the thyristors is the driver (driver circuit). The purpose of the driver is to generate suitable current pulses in order to drive the thyristors; the frequency, phase length, sequence, etc., of these pulses are affected by the [...]
