7.1 Principle

Phase shift control is widely used in applications such as motor control, power supplies, and so on. In TIMA only, asymmetric PWMs can be generated by generating two synchronized center-aligned PWM signals with a controlled phase shift.

To generate Asymmetric PWM, TIMA is required for phase load. Besides, cross trigger is used to synchronize timers. The following is the key feature for the use case.

  • Generate two center-aligned PWMs
  • Use a cross trigger to synchronize two TIMx.
  • Configure phase load (TIMA only)
