June 2003: MITSUBISHI presents the new DIP-IPMs

 The low power IPM's are built in a dual-in-line package for inverter applications featuring direct coupling to the control  circuit without the need for any opto-coupler or transformer isolation. They provide design engineers with a low cost and  compact solution for small motor drives.

 The Dual-In-Line Package Intelligent Power Modules (DIP-IPMs) are targeted for motor inverter drives (also for Hybrid  Electric Vehicles (HEV) and Fuel Cell Electric Vehicle (FCEV) applications) or auxiliary machines. Traditional  DIP- IPMs are mainly used for inverter drives in home appliances such as room air conditioners, washing machines  and refrigerators.

 The new 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 for them 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. Simplified Circuit Design by 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. Reduction of malfunctioning by 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.
