Peripheral Explorer Kit TMDSPREX28335

4 ePWM modules with 8 outputs (4 of them HiRes)

I have never tried it, but it should work except for peripherals that aren't supported (McBSP) 

I am controlling a BLD motor and a magnetic bearing  and i need to send out 9 pwms (6pwms for invert and 3pwms for three electromagnets)so could i use   TMS320F28027 for

this task ? i am quite new with texas instrument, i used to program micrichip microcrontrollers but now i am with texas intrument because it has more experience with motor control.

if your inverter requires the 6 pwms, then no, this device is short a PWM.

However, you might be able to use an eCAP in PWM mode or a GPIO, you'll have to see if they meet your needs.

The 3x ePWM modules will be ideal for your three phase inverter.

thanks for you support.

you argue that 3 epmw should be fine for the inverter, but if the inverter has 6 (IGBT) and ech one needs a single PWM signal, why do you think that

3pwm should be ok? or do you mean that each module has 2 pwms? for that reason i just need 3..

regards david,

each ePWM module consists of a single timer with two PWM outputs.

the outputs will be at the same frequency, but the duty cycles can be complementary or independent, with independent rising and falling edge dead-band.
