Digital driver – proven control platform for IGBT modules and systems
|
Nuremberg, 24 November 2008 - SEMIKRON is the first manufacturer to introduce a multi-functional control platform for IGBT modules and systems. The digital driver SKYPER 52, which has already proven to be a success in driving IGBT modules, is also being used in SEMIKRON systems. This driver boasts a wealth of functions with a minimum of components, making the digital driver even more flexible and robust than before. SKYPER 52 offers a high level of signal integrity, providing reliable immunity from interference signals. The digital driver communicates via CAN input/output, providing the optimum interface between controller and power module. As a result, this driver is particularly suitable for use in systems that integrate power semiconductor, cooling, capacitors, driver and controller hardware.

The SKYPER digital driver transmits the commands of the controller for the power semiconductor with a high level of signal integrity, i. e. clear logic levels. As a result, the resistance to interference factors is improved. The flexibility of this driver is owing to the fact that the switching properties can be programmed individually. Voltage variation can thus be optimised and EMI immunity guaranteed. Complex filter circuits are no longer needed, which saves the user money. Thanks to the increased number of functions offered by SKYPER 52, additional settings such as sequential IGBT turn-off in the event of malfunction are possible.
SKYPER 52 works with low-voltage differential signal transmission, meaning that the gate driver can process the low-voltage 3.3V and 5V controller signals without the use of a level converter. Immunity to interference signals is thereby improved. The powerful SKYPER 52 driver can be used in applications with currents of up to 9000 A and frequencies of up to 100KHZ. The galvanic isolation between the controller and power modules can withstand voltages of up to 4KV. The digital driver is ROHS-compliant and suitable for 1200 V and 1700 V IGBT modules.
In contrast to analog solutions digital technology offers complex functions. “The demand for easy integration of the gate control into converter solutions and the fusion of driver and controller interfaces confirm the need for a digital control platform,” says Johannes Krapp, Product Manager at Semikron.
