I am trying to implement V/F control for 3 phase ACIM using STM32F407 MCU. I am using 6 Complementary outputs of its Adv. Timer 1, Center aligned 256-points PWM waveform. The DC Bus voltage is 600 VDC.
One thing that I am confused about is that since I will be connecting the 3 outputs of the 3-phase Full bridge directly to my ACIM so do i need to generate the 3-Phase -Neutral PWM outputs or 3-Line-Line PWM outputs from the MCU?
