TMS320F28035: Using HIRES-PWM with complementary outputs incl dead time

Part Number: TMS320F28035


Team,

my customer wants to use TMS320F28035 for a 3-phase PWM.

Is it possible to use a PWM (with complementary outputs including dead time) and have both outputs with high resolution?

SPRUGE9E and SPRUGE8E state that the HIRES module only works on channel A after generating the dead time.
That means that the complementary output channel B is only available in "normal" resolution, correct?

Is there a way to have HIRES PWM on both outputs?

Thanks!

    Hi FRAMziskus,

    You are correct- only the A channel has HRPWM capabilities on this device. Your customer will need to use multiple modules (multiple A channels) to achieve this or upgrade to a device such as the F28x7x series.

    Regards,

    Kris
