Ixys Corp. and Siemens AG said they will each draw on the other's manufacturing strengths to jointly develop a series of highly efficient IGBT power modules for industrial AC drives.
Under the terms of the multi-year strategic agreement, Siemens' Electromechanical Components Group will assemble the 600- and 1,200-V modules using Ixys' power semiconductors and direct-copper-bonded (DCB) ceramic substrates. Each company will market the devices using its own brand name and worldwide sales channels.
Ixys described the agreement as a marriage of technologies, which will be sustained by the proprietary nature of power-module construction.
"The footprint and functionality of modules is fast becoming a building block for AC drives," said Rich Fassler, vice president of sales and marketing at Santa Clara, Calif.-based Ixys. "This partnership provides an opportunity to build on someone else's strengths, and provide a second source in the marketplace."
The power modules, which handle current of 5 to 35 A, integrate the three power sections commonly found in motor-drive circuits-three-phase rectification circuitry, inverter circuitry, and an IGBT braking section-into one isolated module to reduce board space and assembly time and cost, and increase power density.
Siemens EC, Munich, Germany, designed the modules using its own rugged non-punch-through IGBTs, incorporating Ixys' planar glass-passivated rectifier diode chips, Fast Recovery Epitaxial Diodes (FREDs), and DCB ceramic substrates. The use of ceramic substrates in power modules provides high isolation between the module's bottom and the silicon inside, and increases power-cycling capability, Ixys said.
The devices are available now in a range of AC-drive power ratings from 250 W to 4 kW.
Ixys is marketing the products under its CBI1 module trade name and the MUBW part number series, while Siemens EC is selling the devices under the name Standard Flow PIM.
In 1,000-piece quantities, the 600-V modules are priced from $25 to $48, and the 1,200-V modules range from $29 to $44.
In the Americas, the Ixys products are carried by All American Semiconductor, Future Electronics, Nu Horizons Electronics, catalog-distributor Digi-Key, and in selected locations by Advacom and Marsh Electronics.
Siemens' power semiconductors and modules are distributed in North America by Insight Electronics, Marshall Electronics, Pioneer-Standard Electronics, and in Canada by Future Electronics.
