Infineon Technologies AG has introduced its new MIPAQ family of IGBT (Insulated Gate Bipolar Transistor) modules that offers a very high level of integration. The MIPAQ (Modules Integrating Power, Application and Quality) products enable highly efficient power inverter designs to be used in Uninterruptible Power Supply (UPS); industrial drives, such as compressors, pumps and fans; solar power plants; and air conditioning systems. The modules are characterized by enhanced testing and are delivered as known-good systems.
“Our system expertise, broad application competence and more than 50 years of experience in industrial electronics, enable us to provide innovative, reliable and energy-saving modules,” said Martin Hierholzer, Senior Director and Head of Industrial Power at Infineon Technologies AG. “Illustrating Infineon’s role as a technology leader in module technology, MIPAQ modules support our customers in mastering the challenge of designing powerful and compact inverters at an excellent price/performance ratio with further enhanced efficiency and ruggedness.”
MIPAQ: A Family of Three
The MIPAQ family is based on an innovative packaging concept and utilizes the advantages of the Infineon IGBT4 chips. These chips feature excellent electrical ruggedness, provide approximately 20 percent lower switching losses than IGBT3 and offer higher power cycling capability. All MIPAQ products feature an IGBT six-pack configuration. The MIPAQ family today includes three products. The modules “MIPAQ base” and “MIPAQ sense” offer significant board space savings. The family members differ in certain functionalities.
For example, the “MIPAQ base” module integrates shunts, while the “MIPAQ sense” module offers an additional current measurement feature that is fully digital with galvanically isolated output signals, and the “MIPAQ serve” module includes adapted driver electronics.
MIPAQ base: The Module with Integrated Shunts
With only 17 mm in height, the “MIPAQ base” modules are ideally suited for use in low-inductive system design in industrial drives, such as compressors, pumps and fans, as well as machine tool inverters. With three specifically designed shunts for current measurement now integrated into the module, these applications greatly benefit from space savings and elimination of PCB hotspots. The integrated shunts now handle all tasks formerly performed by external current sensors, which are costly and require valuable space. The integrated shunts also generate significantly less heat on an inverter’s PCB. The integration into the “MIPAQ base” module provides better heat distribution to the heatsink.
Using Infineon’s IGBT4 chip technology, “MIPAQ base” modules feature a nominal current of up to 150 A in a 1200 V class for the six pack configuration with NTC resistor for temperature sensing. Their maximum operating junction temperature is +150 °C. They are available in Infineon’s EconoPACK3 housing and are RoHS-compliant.
MIPAQ sense: The Module with Digital Current Measurement
In addition to the IGBT six pack configuration and three highly sophisticated current shunts, the “MIPAQ sense” modules also integrate a fully digital current measurement with galvanically isolated output signals using the Sigma Delta measurement method. With Infineon’s Coreless Transformer Technology, optocouplers are no longer required, saving additional board space. The “MIPAQ sense” modules manage currents of 50 A, 75 A and 100 A. They are available in EconoPACK3 housing using PressFIT interconnection technology for fast, reliable and solder-less mounting.
MIPAQ serve: The Module with Adapted Driver Electronics
With the “MIPAQ serve”, Infineon offers highly reliable modules integrating an IGBT six pack configuration, a full set of driver ICs as well as a temperature measurement. These functionalities enable “MIPAQ serve” to be a full plug-and-play solution for high-current drive applications. Inside the module, there are galvanically isolated drivers based on Infineon’s Coreless Transformer Technology. With fewer optical couplers, it will further enhance the modules’ long-term stability. The “MIPAQ serve” modules cover the 1200 voltage range and manage currents of 100 A, 150 A and 200 A.
Samples of the modules “MIPAQ base” and “MIPAQ sense” are expected to be available in Q3 2008 with start of production scheduled for Q2 2009 (MIPAQ base) and for Q3 2009 (MIPAQ sense). Start of sampling of “MIPAQ serve” modules is projected to begin in Q4 2008 and start of volume production in Q3 2009.
Infineon Technologies AG, Neubiberg, Germany, offers semiconductor and system solutions addressing three central challenges to modern society: energy efficiency, communications, and security. In the 2007 fiscal year (ending September), the company reported sales of Euro 7.7 billion (including Qimonda sales of Euro 3.6 billion) with approximately 43,000 employees worldwide (including approximately 13,500 Qimonda employees). With a global presence, Infineon operates through its subsidiaries in the U.S. from Milpitas, CA, in the Asia-Pacific region from Singapore, and in Japan from Tokyo. Infineon is listed on the Frankfurt Stock Exchange and on the New York Stock Exchange (ticker symbol: IFX).
