3ph inverter 6 IGBT gate pulse using STM32F407 disco TIMER?

[parth kothiya]

i want to make 3ph inverter for induction motor speed control i cant understand how to generate 6igbt gate pulse with PWM using stm32f407 disco board timers have only 4-chanel.

Dear parth kothiya

Do you have still this problem to solve?

[parth kothiya]

yes i am facing this problem still now.

Thank you for giving attention on my question.

can you please provide any suggestion or example it is really helpful to me.

I also want to protect my firmware using encryption.

Dear @parth kothiya​ 

Do you work with STM32 Motor Control SDK?

Dear @parth kothiya (Community Member)​ 

Could you give more details to the STM32 Community about the material you use (HW and SW, CPU(s), tools and versions, board(s), motor(s) and so on)?

And more especially did you use MC tools (such as MC_suite, MC-Motor Profile, MC-SDK, MC-workbench, and so on)?

Dear @parth kothiya​ 

As you do not answer, I guess you don't have to solve this problem anymore, therefore I consider this thread closed.

If not, feel free to reopen it by posting an answer.

Dear @parth kothiya​ 

There is now in the last SDK version demonstration firmware example projects for ACIM showing how the STM32 MC SDK can be used to drive an asynchronous induction motor (ACIM) in field-oriented control (FOC) using a sensorless state observer algorithm to estimate the electrical and mechanical speed and position of the rotor and the rotor flux, or in V/F open-loop sensorless mode.

Please have a look on our STM32 Motor Control Knowledge database here: https://wiki.st.com/stm32mcu/wiki/STM32MotorControl:SDK_AC_induction_motor .
