November 29, 2001

C&H Technology and International Rectifier Corporation introduced a new series of 320A and 400A standard-recovery, stud-mount rectifiers in the DO-9 package. The new devices expand IR's current line of DO-9 rectifiers with ratings from 50V to 3,200V and 300A to 400A. The devices are made for high-voltage, high-current industrial applications such as welding, battery chargers, power supplies and light-duty traction applications. These rectifiers are manufactured with a new process that combines brazed-die construction with compressed assembly. The new devices feature power-cycling performance and the ability to maintain stable forward-voltage characteristics.

NEW PRODUCTS

International Rectifier's program of continuous improvement has enabled the release of a new generation of high power SCR and Diode modules, the INT-A-PAK GEN II DBC (direct bonded copper) MODULE, a direct replacement of the previous Compression Bonded module.  Their new DBC Gen II modules will provide the following characteristics:

    • Light Weight Construction
    • Copper Base for added mechanical strength
    • Improved Process Control and Automated Production
    • Complete Mechanical Compatibility to Gen I
    • High Reliability

The new Int-A-Pak DBC Gen II modules are designed to satisfy both the needs of the traditional Int-A-Pak market, as well as newer applications, such as motor drives, battery chargers, UPS, and the emerging welding market, where the circuitry is typically based on bridges and AC switches.

New Soft Start Controller Offers Revolutionary Power Conversion Solution for AC Input ConvertersInternational Rectifier has introduced a SOFT-SMART MOTOR CONTROLLER IC. The IR1110 is tailored for motor drives of 10HP and higher. Secondary markets for the new IC driver are Welding, Induction Heating, UPS and Power Supply.
  • Key functions and features include:
  • Limits in-rush short circuit current
  • Regulates DC Bus voltages
  • Protects and increases reliability and lifetime of DC Bus  Capacitor
  • Fast ramp-back recovery after temporary power loss
  • 75% less board space than traditional soft change methods
  • Up to 100% higher power at low motor speeds
