    2SP0115T Gate Driver Unleash the full power of your converter design using the new 2SP0115T Plug-and-Play driver. With its direct paralleling capability, the scalability of your design into highest power ratings is unlimited. Rugged SCALE-2 technology enables the complete

    the size of 17mm dual modules. Combined with the CONCEPT advanced active clam- ping function, the electrical performance of the IGBT can be fully exploited while keeping the SOA of the IGBT. Needless to say that the high integration level provides the best possible reliability by a minimzed number of components.

    Features Plug-and-Play solution 1W output power 15A gate current

  • Next generation inverter designs for renewable energy applications

    demand reliable DC link capacitors with higher capacitance values,

    voltage, and current ratings. Now available in new case sizes, Cornell

    Dubilier’s expanded range of Type 947C power fi lm capacitors meet or

    exceed the requirements for bulk energy storage, ripple fi ltering and life

    expectancy for wind and solar power inverter designs, as well as electric

    vehicle applications. Select from hundreds of standard catalog listings,

    or connect with CDE engineers to develop special designs to your

    requirements.

    Welcome to this issue of PSD where we present a special feature on renewable energy.

    The focus on renewables - and especially energy harvesting, has certainly hit the industry’

    s headlines over the past year. Apart from being good for the environment and good for the

    power electronics industry, it is a sought after lever for governments and administrations to

    attract ‘clean votes’. With previous waves of engineering graduates trained in analog, logic

    and DSP technologies, maybe the next wave will be qualified as energy harvesting experts

    encompassing all of the above. It most likely hangs on the investment made now in education

    at this level, which probably depends heavily on the state of the economy and government

    priorities, to use a broad-brush term. Hopefully this relatively new industry will spawn the next

    wave of valuable and talented engineers who will take up and solve the real challenges facing

    our energy-hungry environment.

    After nearly two years of unimpressive performance, the recovery of the global market for

    Uninterruptible Power Supplies (UPS) is picking up momentum. The industry on 3Q-2010

    performed 12.9% higher than 3Q-2009, according to IMS Research. There were strong UPS

    sales in Asia and the Americas, while the debt crisis in Europe is still hampering its revival.

    China and India remain the engines of growth in Asia with a rapid uptake in shipments across

    all sectors. Without question, Asia is now a major focus of supplier attention. In the span

    of five years, Asia has grown its share of the global market from 25% to 33%. The market

    in Europe, Middle East and Africa has not improved to the degree of those in Asia and the

    Americas, where UPS revenues remain roughly the same as in 2009.

    The rapid recovery in automotive production and inventory rebuilding among sensor

    component suppliers has set the market for automotive MEMS sensors to expand to record

    size in 2010, according to iSuppli. Marking a new high-point for the industry, shipments

    of automotive MEMS sensors will reach 662.3 million units in 2010, up 32.1% from 501.2

    million units in 2009. The recovery in automotive MEMS shipments represents a turnaround

    from the depressed levels of 2009 when shipments reached a nadir, and the years ahead will

    provide additional room for expansion. One significant source for automotive MEMS growth

    is the use of sensors in passenger cars supporting mandated safety technologies such as

    electronic stability control (ESC) and tyre pressure monitoring systems (TPMS). The United

    States and Europe lead the adoption of legislation on such safety systems – with many other

    countries following suit.

    I hope you enjoy this issue with the ongoing improvements to the magazine and website design

    based on your valuable feedback. And please check out Dilbert at the back of the magazine.
