Infineon - REF-DR3KIMBGSICMA

Infineon – REF-DR3KIMBGSICMA

The SiC reference design REF-DR3KIMBGSICMA is the combination of an inverter board and a gate driver board for the demonstration of an integrated servo motor and drive. The driver circuit is based on EiceDriver™ IC -1EDI20I12MH with Miller clamp function. CoolSiC™ MOSFET –IMBG120R45M1H is the main component for the 3-phase inverter.To evaluate the electrical performance of the system, the iMOTION™ MADK EVAL-M1-101T can be used to provide a simple control.

Features
– 1200 V, 45 mΩ CoolSiC™ MOSFET in SMD package (TO263-7L), with .XT interconnection technology
– 3-phase servo motor with integrated drive
– IMS (Insulated Metallic Substrate) PCBs with high thermal conductivity
– Input voltage 350 –800 VDC
– Output voltage 220 VAC, 380 VAC, 480 VAC

Target applications
– Motor control and drives
– Servo motor drive and control

Benefits
– Possible for passive cooling without cooling fans
– Ultra small footprint with a PCB diameter of 110 mm
– High power density
– Overcurrent protection

Competitive advantage
– A reference designs, which helps to design outdoor units (ODU) more efficient, denser and faster : – Efficiency -Excellent PFC performance with a power factor (PF) of 0.999 and a total harmonic distortion (THD) of 3.4% at 1.4 kW
– Size -Up to 15% smaller design compared to discrete implementation
– Speed -Reduced time to market by concentrating on application development rather than on motor control
