Mitsubishi Electric Introduces World's First Super High Reliable DIP-IPM
Product



Tokyo, Japan, June. 19, 2003 - (JCN Newswire) - Mitsubishi Electric
Corporation today introduced a super high reliability
Dual-In-Line Package Intelligent Power Module (DIP-IPM) targeted for
motor inverter drives of electric car air conditioners and other Hybrid
Electric Vehicle (HEV) or Fuel Cell Electric Vehicle (FCEV) auxiliary
machines. This DIP-IPM product is the first of its kind in the world. 

Traditional DIP-IPMs are mainly used for inverter drives in home
appliances such as room air conditioners, washing machines and
refrigerators. The super high reliability DIP-IPM is also suitable for
automobile applications, thus contributing to the miniaturization of
automobile inverter drive systems. 

The increased use of energy-saving air conditioners in green automobiles
(HEV, FCEV) is in response to environmental concerns. To meet this need,
smaller and more reliable IPMs are required in the inverter drives of
electric car air conditioner compressors and other auxiliary motors. The
application of DIP-IPMs in electric automobiles is expected to
contribute to the miniaturization of inverter drive systems in other
auxiliary motors as well. 

There are three main features for this application:
1. High Reliability with Reduced Mounting Surface Area 
Development of high quality IPMs should improve product performance in
harsh environmental conditions. Failure probability has been greatly
minimized through quality control management. The temperature cycle
capability has been improved considerably by employing the new structure
power chips (IGBT[2]£¬FWD[3]£¬HVIC[4]£¬LVIC[5]). By using the new IPM,
the mounting surface area of the device and its interface circuit is
reduced by about 40 percent, compared with traditional IPMs with the
same 30A/600V rating. This results in considerable space savings.

2. High Active Drive Logic
The start up sequence of the control supply is required as a
countermeasure against possible malfunctions during the control supply
power on-and-off period in a traditional IPM system. With the high
active drive logic, this requirement is no longer necessary.
Furthermore, the new approach offers a versatile interface compatible to
3V class MCU or DSP.

3. EMI[6] Noise Reduction
By optimizing the switching speed, EMI noise in the new DIP-IPM has been
reduced by about 10db in comparison with traditional products.

Availability
Product (PS21867-AJ) samples will be available in March 2004 at 5,000
Japan yen per piece with monthly mass production of 20,000 pieces
scheduled to begin from January 2005.
__________
Definitions
[1] Transfer-mold --Injecting heated and pressurized resin to a sealed
container (metallic mold) then applying pressure to form the shape. The
productivity is highly efficient since multiple shaping is possible in a
single process. 
[2] Insulated Gate Bipolar Transistor --Power device with features
suitable for high switching operations and voltage drives similar to
MOS-FET, and low on state voltage like that of a bipolar transistor. 
[3] Free Wheeling Diode --Diode for carrying freewheeling current
[4] High Voltage Integrated Circuit --Integrated circuit with blocking
voltage over 50V for the drive and protection of switching semiconductor
devices.
[5] Low Voltage Integrated Circuit --Integrated circuit with blocking
voltage under 50V for the drive and protection of switching
semiconductor devices. 
[6] Electromagnetic Interference --The electromagnetic waves generated
by electronic machines interfere with the proper operation of other
electronic machines.
