In the future it will be possible to use IGBT High Power Modules (IHM) from Infineon Technologies AG even longer. More robust construction and greatly improved thermal conductivity behavior increase the average life time in comparison to previous models by a factor of up to 11 under the same conditions of use. A major advantage here is that the electrical and mechanical parameters of the module remain the same in spite of the necessary changes involved. As a result there is no need for recertification and the qualification scope is minimized to an extreme extent.
Customers therefore benefit from the greater robustness and reliability of the IHM product family with very low development work or expenses. Another differentiation feature for customers: In spite of the considerable product improvements, the sale price has been kept at the same level. The new IHM-B Enhanced modules will go into volume production in August 2014.
The significantly longer life time of the IHM-B Enhanced modules is based on two central modifications. First of all, a newly implemented manufacturing technology enables more robust bond wire connections. This increases the resilience of the module components in power cycling associated with switching. The power cycling behavior of the IHM-B Enhanced has improved by a factor of two compared to the previous model.
Secondly, the thermal conductivity of the IHM-B Enhanced is increased by the combination of an aluminum silicon carbide (AlSiC) base plate with aluminum nitride (AlN) substrates. Depending on the topology used, the thermal resistivity drops by 16 – 18 percent:For example, with a 2400 A single switch module this means an improvement from 9.3 Kelvin per kilowatt (IHM-B) to only 7.8 Kelvin per kilowatt (IHM-B Enhanced). Significantly better dissipation of heat generated during operation of the module relieves in particular components susceptible to heat, such as chips and bond wires.
"With the IHM-B Enhanced modules we are introducing a new manufacturing technology and a new substrate material. These advances have proven themselves in practical testing since the end of 2012 with challenging applications such as wind mills," saysBjörn-Christoph Schubart, responsible for IGBT High-Power Modules at Infineon. "We've created value by clearly prolonging service life with otherwise unchanged product properties and will continue to expand our excellent position in the High-Power Module sector. The high levels of product reliability and price stability are of particular benefit to our customers in growth markets such as transport, industrial drives and renewable energy."
Portfolio and Availability
The new IHM-B Enhanced modules are available in the topologies Single Switch, Chopper, Chopper with Inverted Diode and Dual-Diode. In the IHM product portfolio, modules of the 1700 V voltage class will be upgraded first in the range of from 800 A to 3600 A. This conversion is to be completed by August 2014.

Meet Stratumn, a Paris-based startup that wants to create a platform-as-a-service for developers interested in the blockchain. With Stratumn, you can build, deploy and run applications on the company’s platform, and these applications can communicate with the bitcoin blockchain. It’s like Heroku, but for blockchain developers.
The company just raised $670,000 (€600,000) from Otium Venture and business angels, such as Ledger Wallet CEO Eric Larchevêque.
At heart, the bitcoin blockchain is a distributed database that registers all bitcoin transactions with a timestamp. Many have taken advantage of the blockchain to build applications that were unrelated to bitcoin transactions.
For instance, Stampery wants to replace notaries with the bitcoin blockchain. The service can issue legally binding proofs for all your sensitive documents, and these proofs live on the blockchain.
But Stratumn is taking this idea one step further and saying that other startups like Stampery are going to appear. Instead of having to redo the hard work from scratch, Stratumn lets your application talk with the blockchain without any effort from your side.

Fuji Electric Co Ltd will commercialize a SiC MOSFET by using it for a PV inverter for mega (large-scale) solar power plants.
Fuji Electric will start volume production of the PV inverter in August 2014. Its input voltage and output capacity are 1,000V (direct current) and 1,000kW, respectively. The company has already commercialized a SiC diode. This time, it applied a power module equipped with the diode and SiC MOSFET to the boost circuit of the PV inverter to improve conversion efficiency and reduce size.
The conversion efficiency of the PV inverter is 98.8%, which Fuji Electric claims is the highest in the industry. The conversion efficiency of the company's previous PV inverter product is 98.5%. The dimensions of the new PV inverter are 2,980 x 1,900 x 900mm, which is 20% smaller than the size of the previous product.
With at least 38.4 gigawatts (GW) of newly-installed solar photovoltaic (PV) capacity worldwide and a global cumulative installed capacity of 138.9 GW, 2013 was another historic year for solar PV technology. EPIA’s flagship report assesses global and European PV markets in 2013, makes forecasts for the next five years, and analyses the role of PV within the European energy sector.
Munich, 02 June 2014 – The European Photovoltaic Industry Association (EPIA) released today its new report “Global Market Outlook for Photovoltaics 2014-2018”. Compared to the two previous years, where global installed capacity hovered slightly above 30 GW annually, the PV market progressed remarkably in 2013, reaching a new record-level. Nevertheless, for the first time since 2003, Europe, with a very high and stable level of nearly 11 GW connected to the grid in 2013, lost its leadership to Asia. PV markets have become global!
EPIA’s major findings for 2013 include:
At least 38.4 GW of PV systems were installed globally in 2013, up from 30 GW in 2012Almost 11 GW of PV capacity were installed in Europe in 2013, compared to 17.7 GW in 2012China (11.8 GW) was the top market in 2013, followed by Japan (6.9 GW) and the USA (4.8 GW)Germany was the top European market with 3.3 GW. Several other European markets exceeded the one GW mark: the UK (1.5 GW), Italy (1.4 GW), Romania (1.1 GW) and Greece (1.04 GW)PV now covers 3% of the electricity demand and 6% of the peak electricity demand in EuropeSeveral European markets that performed well in the past went down in 2013: Belgium (215 MW), France (613 MW) and Denmark (200 MW)Outside Europe, several markets continued to grow at a reasonable pace, including India (1,115 MW), Korea (442 MW), Thailand (317 MW) and Canada (444 MW)
EPIA forecasts indicate that the globalisation trend of PV markets observed in 2013 will continue and further accentuate in the coming years. “The forecast for Europe in the next years should, however, be put into perspective and be considered as a stabilisation towards a solid level, around 10 GW a year,” stated Oliver Schäfer, EPIA President, during the launch of the report at the Intersolar Europe Opening Session. “Europe’s situation at the end of last year shows that PV, as any other energy business, remains policy-driven. A series of retrospective measures were implemented in the last years in various European countries, leading to the sharp market decrease observed in 2013. Sustainable, predictable and dynamic framework condition and policies are needed in Europe and globally to provide enough visibility to investors,” he added.
For the third year in a row, PV in 2013 was amongst the two most installed sources of electricity in the EU. “PV is becoming a major part of the electricity system all over the globe, changing the way our world is powered. Policymakers and energy stakeholders should now understand that electricity grids and markets need to be adapted to fit these new realities and facilitate a cost-efficient energy transition,” concluded Mr. Schäfer.
