Mitsubishi Electric to sell New-MPD series of IGBT modules

TOKYO, JAPAN: Mitsubishi Electric Corp. has launched its "New-MPD (Mega Power Dual) Series" of insulated gate bipolar transistor (IGBT) modules. Suitable for all applications requiring high power density, the New-MPD modules are mainly for use in power converters for large capacity wind power and photovoltaic (PV) systems.

Shipments will begin in January, 2010 through Mitsubishi Electric sales sites in Americas, Europe, China, Korea.

Power generation systems now focus on natural energy sources such as wind power or solar power in order to limit carbon dioxide (CO2) emissions and reduce global warming. Recent trends have seen the appearance of large-scale, megawatt-class power generation systems, and the power conversion equipment used in such systems requires higher power than before.

In 2002, Mitsubishi Electric released its original MPD series featuring 2-element, 1,400A/1,200V IGBT modules that could handle megawatt-class power generation. The company has released the New-MPD Series to accommodate the expanded volumes handled by power generation systems. The New-MPD Series products can also be utilized in large capacity inverters and uninterruptible power supply (UPS) systems for industrial equipment.

Product features:

* Current rating extended to 2,500A by using dedicated package and sixth generation IGBT
The current rating exceeds that of the original MPD series by 1.5 times, and features a dedicated package with a rearranged internal structure and 6th generation IGBT chips. CM2500DY-24S's current rating of 2,500A is the highest in the industry among 2-element IGBT modules, as of the date of announcement.

* An optimum chip layout with adequate surrounding margin improves cooling efficiency in liquid-cooled applications
To improve cooling efficiency in liquid-cooled applications, each chip within the package has been surface-mounted plate with an adequate surrounding margin.

* Environmental consideration
The New-MPD Series is compliant with the "Restriction of the use of certain Hazardous Substances" in electrical and electronic equipment (RoHS).
