Achieved world-leading level of power loss reduction and down-sizing "New Dual", a New Product Line of Fifth Generation IGBT Modules U4 Series

Fuji Electric Device Technology Co., Ltd. (President: Akira Takai) announced today that it will release New Dual, a new product line of the fifth generation IGBT modules U4 series from July 2006. The U4 series was released last year and boasts world-leading performance.

In addition to the existing feature from the U4 series that achieves a better trade-off between noise reduction and lower power loss (power loss was reduced by 30% compared with conventional products), New Dual will come in much smaller and thinner package by applying the latest high-heat dissipation substrate. This will realize downsizing and efficiency improvement of the equipment and devices that require IGBT modules. The voltage and current ratings of New Dual are 1200V/225A, 300A and 450A.

This new product line targets the following areas: inverters used in the industrial infrastructure field where future growth is expected; power conversion equipment for wind power generation systems in the alternative energy field; and large-scale uninterruptible power supplies in the information technology field. Fuji will actively market this new product line for these applications aiming at selling 10,000 units in the first year.
