Hi,
I'm trying to find pointers on how to implement control of a LMG5200 half bridge with high-side + low-side signals using N2HET and HUT.
Most links to HET examples seem to be dead.
Are there any examples available?
Thanks,
Geert
Hi Geert,
You can generate 2 PWM signals using ECMP and MOV64. It is pretty straightforward. What is your specific question?
Hi Geert,
The TMS570LS1224 has ePWM module. Can you ePWM to generate PWM signals?
Attached is an example of 3-channel PWMs with dead-zone. You can use this as a reference:
You can use HED IDE to test the code, and modify the mode for your use case.
Hi,
We are generating a sine wave with variable frequency around 20KHz using HET and HTU on one HET pin. Now we want to make it a symmetrical pair.
The ETPWM seems perfect to generate a symmetrical pair with dead time from Halcogen but unfortunately it seems to slow for our waveforms.
Thanks for your quick response.
The ePWM module uses VCLK4, the generated PWM freq can be >MHz.
You can use the example I posted yesterday.
