SUMMARY

The discussion centers on selecting appropriate IGBTs and drivers for a 1200W DC/AC inverter project designed to run a small induction motor. The user has successfully generated a sine PWM signal using a PIC18F2331 microcontroller but seeks guidance on the specific transistors and drivers suitable for their application. Recommendations include consulting datasheets and tutorials for comprehensive inverter design, emphasizing that inverter design encompasses more than just transistor selection.

PREREQUISITES
  • Understanding of sine PWM signal generation using microcontrollers, specifically PIC18F2331.
  • Familiarity with IGBT specifications and datasheets.
  • Knowledge of inverter design principles and components.
  • Experience with driver circuits for IGBTs.
NEXT STEPS
  • Research specific IGBT models suitable for 1200W applications, such as the IRG4PH50KD.
  • Explore driver ICs compatible with IGBTs, like the MIC4427.
  • Study inverter design tutorials, particularly the one linked in the discussion.
  • Investigate thermal management techniques for high-power inverter applications.
USEFUL FOR

Electrical engineering students, hobbyists designing inverters, and professionals involved in power electronics who require guidance on IGBT selection and inverter design.

Hello...
i have a small project in the university concerning sine wave dc/ac inverter.
i want to run a small induction motor, so the maximum power of the inverter is 1200w.
i did the control part and i generate a sine pwm signal from pic18f2331 microcontroller, but my problem with the IGBT and their drives.. really i don't know which transistor and which drive to choose for my application.
If anyone has information about the type and the data sheet of any transistor and their drives please reply.
thank you
