IGBT Modules claim Maximum Efficiency and Reduced Power Loss

Fuji Electric has announced the addition of a new IGBT module series to their semiconductor product portfolio, with the latest modules featuring advanced T-type neutral point clamped (AT-NPC) 3-level 12-in-1 circuit systems to significantly reduce power loss. This latest innovation comes three years after the manufacturer originally developed the AT-NPC 3-level circuit system, which they used in IGBT modules one year later in 2011. The company's new IGBT modules contain essential circuitry to drive power electronic equipment in a single package, which enables reductions in the size of power electronic equipment by taking up less space than the sum of three conventional models.

“Through the use of Fuji Electric’s proprietary RB-IGBTs, we were able to eliminate reverse blocking diodes,” said Steve Bottari, General Manager of Fuji Electric’s Semiconductor Department. “These improvements significantly reduce power loss and achieve high efficiency power conversion, both of which are key for applications such as inverters, UPS, and power conditioners for residential photovoltaic systems.”

The size reductions made possible by the single module are substantial, taking up 60% less mounting space in equipment such as inverters and uninterruptible power system equipment than using a combination of conventional modules. Using Fuji Electric’s RB-IGBT technology, power loss is reduced by 50%*. In addition, there are two types of terminal pins available, accommodating product lineups equipped with solder pin or press-fit pins, depending on customer’s assembly lines.

“We continue to invest in research and development so that we can maintain our position as a global leader in power electronics manufacturing,” said Phil Charatz, President and CEO of Fuji Electric Corp. of America. “This ground-breaking technique has been received accolades around the world, and was awarded the 60th OHM Technology Award of The Promotion Foundation for Electrical Science and Engineering.”
