IGBT Driver offers individual control parameter settings.July 23, 2008 -
Suitable for 1,200 and 1,700 V IGBT modules, RoHS-compliant SKYPER® 52 allows for transmission of isolated sensor signals and individual protection level settings. Use of differential digital signal processing enables switching characteristics, shut down levels, and error processing to be set to meet application requirements. Dual 9 W output channels and peak gate current up to 50 A make product suitable for parallel connected IGBT modules with total current up to 9,000 A.

The New Digital Driver SKYPER® 52 Offers Individual Control Parameter Settings and Controls Parallel Connected IGBTs with a Total Current of up to 9,000 A
Nuremberg, 15 May 2008 - Semikron has unveiled a new IGBT driver generation. The new driver SKYPER® 52 is based on fully digital signal processing, allowing for the transmission of isolated sensor signals and individual protection level settings. This means that development engineers can do away with costly discrete isolated circuits. The result is fewer system components and improved overall system reliability.
Differential digital signal processing not only provides numerous technical advantages but also ensures a high level of signal integrity and hence high noise rejection. With the digital driver SKYPER® 52, switching characteristics, shut down levels, as well as error processing can be set to meet the given application requirements. In other words, this driver is a unique flexible IGBT driver. Digital signal processing does not depend on the component parameters, is highly robust and is unaffected by temperature fluctuations or the affects of ageing. For development engineers this means flexibility with the driver circuitry properties and, consequently, the control settings for the power electronics, which can be adapted to meet the individual needs. If an error is detected, this then means that all of the power transistors can be switched off either individually or sequentially. Overvoltages, especially those that occur in short-circuit turn-off conditions, are reduced by the IGBT driver. To do so, the driver switches the power transistor smoothly. This is possible thanks to intelligent turn-off control. Furthermore, with the new graphic interface GUI (Generic User Interface) Semikron customers can enjoy the benefits of a user-friendly configuration platform that can run on Linux, Mac OS X or Windows systems. "The changeover to a digital driver means we can now give our customers all the benefits of digital technology in combination with the unmatched properties of our IGBT drivers," explains Markus Hermwille, Senior Product Manager of the Electronics division at Semikron.
The digital driver SKYPER® 52 is RoHS compliant and suitable for 1200 V and 1700 V IGBT modules. It has two 9W output channels and a peak gate current of up to 50 A, making it suitable for parallel connected IGBT modules with a total current of up to 9,000A. SKYPER® 52 is also suitable for high-frequency applications that require high driver output power and switching frequencies (up to 100 kHz).
The insulation voltage is 4 kVAC and the turn-off voltage -15 V. The rugged LVDS-compatible and hence differential signal inputs and outputs correspond with the 3.3 V and 5 V I/O standards. The driver circuit can therefore be directly connected to a micro-controller or DSP without level conversion.
