SEMIKRON SKYPER Prime IGBT driver

Click2Contact

SKYPER Prime is an IGBT driver for Semitrans 10 and PrimePACK modules. Apart from control and protection functions, the IGBT driver offers galvanically isolated voltage and temperature signals. The absence of external power supplies, isolation or acquisition boards saves up to 10% of the system cost.

The sensor signals are available as PWM and allow direct connection to the controller. Extra A/D conversion, reducing the accuracy, is omitted. Due to the integrated overtemperature and overvoltage turn-off in connection with the no-tolerance fault management, the IGBT module can be safely operated at its performance limits.

SKYPER Prime drives Semitrans 10 package modules up to 1400 A and 1700 V. The operating area is tailored to the respective module and allows an increase in output power of up to 30% compared to existing solutions. This saves on safety measures and provides performance advantages. Accurate switching behaviour due to digital signal processing, fault management for parallel operation and symmetrical signal distribution provide for maximum output power.

The SEMIKRON ASIC chipsets integrated achieve an MTBF rate of >3 million hours at full load. Power supply, protection and driving functions are included in the ASIC chipset and external output stages ensure optimal thermal decoupling. The isolated information is transmitted via digital signals and is very robust, even at high dV/dt. The driver thus operates safely even up to 4 kV interference on the signal lines.

The SoftOff function and the VCE monitoring protect against overvoltage in case of a short circuit without the tolerance constraints of clamping circuits. Due to the short pulse suppression and an interface ground concept, high EMC stability is achieved. With the integrated sensor signal processing available to the user as digital signals and the ease of paralleling, the product offers an IGBT driver solution for high-power applications in the megawatt range.
