Hi TI Team,
I am trying to replicate the ALM2403-Q1 schematic design simulation in TINA TI as shown in the below application note.
I'm not able to replicate the exact sinusoidal PWM input in TINA TI as shown in the above image.
If possible please share me the PWM sinewave file(f sw_320kHz = 320 kHz, 3.3 Vp-p).
Thank you
Hi Sangeetha,
If possible please share me the PWM sinewave file(f sw_320kHz = 320 kHz, 3.3 Vp-p).
Here are two examples how SPWM signal can be simulated and filtered out. One is using comparator and other one is using behavior model to generate the SPWM signal and the excitation sinusoidal waveform. The latter one is more flexible for the simulation purposes.
In the thread below, we discussed the MFB for the application note. Perhaps it is useful to you.
Enclosed is similar resolver simulation with two SPWM GPIO ports. The one published in the application note is using a single SPWM or SPWM generator to generate the 10kHz sinusoidal waveform.

If you have other questions, please let me know.
Best,
Raymond
