TIDM-02000: PSFB(Phase shift full bridge) leading leg & lagging leg change.

Part Number: TIDM-02000
Other Parts Discussed in Thread: TMS320F280039,

Tool/software:

Hello. I am Sam.

I am developing PSFB DCDC convertor using TIDM-02000 and using TMS320F280039.

With Reference to TIDM-02000, ePWM2A/B is leading leg and ePWM1A/B is lagging leg.

I would like to change the leading leg to ePWM1 and the lagging leg to ePWM2.

In the code below, I changed PSFB_FB_PWM1_BASE to EPWM2_BASE and PSFB_FB_PWM2_BASE to EPWM1_BASE to check switching, but it did not work.

The SR switch was turned off and tested.

Is there anything else I need to do to change EPWM1_BASE and EPWM2_BASE?

Thank you.
