SKYPER 42 boasts three times the service life of standard drivers for use in inverter systems with outputs of up to 1.5MW
The new SKYPER 42 is a highly robust driver for control of 400 – 2000 Ampere IGBT modules. Boasting a mean time between failures of more than two million hours, the service life of this driver is triple that of standard IGBT drivers. The optimised layout featuring unique electromagnetic shielding and integrated short-pulse suppression guarantees protection from external interference. The SKYPER 42 driver charges up to 50µC, making it suitable for use in inverter systems up to 1.5MW.
Ruggedness starts with the controller side of the driver. The SKYPER 42 driver switches at interference-free 15V and uses short-pulse suppression to reject pulse interference. Signal and power transmission is done by way of purpose-developed transformers which, thanks to their very low coupling capacitance, display twenty five percent more voltage resistance than conventional IGBT drivers. The control voltages for the IGBTs are stabilised on the secondary side, thus enabling steady and reliable IGBT module control. The optimised mass concept and the shielded PCB enable a hundred percent increase in interference immunity over the levels specified in the EN standard.
Thanks to extensive qualification measures and application-like conditions throughout the entire development process, the SKYPER 42 driver achieves a MTBF as per SN29500 of more than two million hours, making it last three times as long as a standard IGBT driver.
SKYPER 42 is a dual-channel IGBT driver for 600V, 1200V and 1700V IGBT modules. With a maximum output current of 150 mA and a maximum switching frequency of 100 kHz, this driver is suitable for IGBT modules of up to 2000 A.
The use of integrated power and signal transformers means that the customer no longer has to include his own costly, discrete isolation solutions or corresponding protection which is needed in driver ICs. The integrated power unit concept generates the +15/-8V gate voltage from 15V input voltage, meaning the customer needs no additional power units.
Easy integration into your system is possible thanks to the use of SKYPER 42 adapter boards. IGBT triggering is symmetrical and, in the case of modules connected in parallel, carried out with separate signals for each chip. This reduces voltage and current peaks and enables highly efficient module control which makes full use of the potential offered by new, fast switching IGBT chips. Additional measures for overvoltage reduction such as active clamping are thus superfluous.
The SKYPER 42 driver was developed on the basis of years of experience in this market with the SKYPER 32 and 52 drivers. The need for low heat build-up, high resistance to external interference, compact dimensions and easy integration - key requirements across various industrial areas - were factored into the development of the new driver. The result is SKYPER 42, a reliable dual-channel IGBT driver that will weather out any industrial life cycle.

New Semikron 1200 Volt IGBTs available from PPI Ltd.
A new low-inductance 1200V IGBT module series, for use in AC/DC converters in the 20 to 300kW power range, has been introduced by Semikron.
The Semitrans modules are available with Fuji fifth-generation V-IGBT chips as an alternative to IGBT4 chips. The very low 15nH module inductance offers two advantages: 50V higher DC link voltage than in competitor modules, due to the lower switching over-voltages; plus faster and softer IGBT switching producing lower switching losses, boosting overall efficiency
In addition to the existing Semitrans modules with IGBT chips from Infineon, Semitrans modules now also are available with V-IGBT’s from Fuji, offering a blocking voltage of 1200V. The new V-IGBT based modules are available in three different sizes, a total of eight different power classes and three switching topologies, with rated currents of 150A to 600A. Semitrans 3 and 4 modules are very low-inductance modules with a module inductance of just 15nH. The typical IGBT switching speed of 5000A/µs results in a module overvoltage of just 75V. Competitor products produce on average module over-voltages of between 90V and 125V. The modules come in single-switch, half-bridge or chopper topology for inverters in industrial drives or any other application area.
SEMIKRON APPOINTS FRANCHISED DISTRIBUTOR
"SEMIKRON has seen significant growth over the past two years, both internationally and in the UK, and consequently have reviewed how best we can service our customers with regard to stock and material logistics, faster lead times plus product support. This process has seen a new central European warehouse set up twelve months ago, and the implementation of direct deliveries to customers where transportation costs are economical."
"We are however mindful of the longstanding objective SEMIKRON has, of supporting all of our customers, from individual users through to OEMs. To ensure the continuity of this goal, we have appointed Power Products International Ltd (PPI Ltd) as our franchised UK distributor. This agreement includes a range of working stock and direct supply to our current customers that require infrequent and short term deliveries, and where transport costs would not justify direct shipment from the central hub."
"PPI are well known in the industry and, working very closely with SEMIKRON, will, I am sure, prove to be an excellent supplier to you. SEMIKRON see PPI effectively as an extension to our sales team and will support them in every way."
