This solution integrates Infineon's seventh-generation IGBT7 module, driver IC, auxiliary power supply using 1700V SiC-MOS, and power ICs into a frequency converter scheme.
Features
- Utilize IGBT PIM modules to achieve the technical advantages of IGBT7
- Use Infineon's isolated driver ICs to avoid the optical attenuation issues of optocouplers
- The auxiliary power supply employs a 1700VSIC-MOS with high-power output
Applications
- Fan and Pump System
- Compressor and Air Compression System
- Industrial Conveying and Transport Equipment
Benefits
- By using the IGBT7 module, losses can be reduced, and the working junction temperature of Tvjop can be allowed to reach 175 ° C during short-term overload, thereby improving the power density of the system.
- Simpler driver power circuit design
- Compact design, compared to IGBT4, can provide a smaller package with the same current
- dv/dt is optimized for controllability in the 2-8kV/µ s range, suitable for motor driven applications
