  • TIDM-02000: About static inline function purpose

    Resolved
    Part Number: TIDM-02000 Hi, 1) Why did TI used "static inline void PSFB_pcmcControlCode(void)" instead of using " void PSFB_pcmcControlCode(void)"? Could you please explain basic and main purpose of using static inline? 2) This static…

  • TIDM-02000: PWM2 configuration with PCMC=0 and PCMC=1

    Part Number: TIDM-02000 Hi, I investigated the software for TIDM-02000. 1) What is the meaning of PSFB_PCMC=0 and PSFB_PCMC=1? How does they differ from each other? 2) At ePWM2 configuration; I saw following lines. If PSFB_PCMC=0 ; EPWM_setTimeBasePeriod…

  • TIDM-02000: Question ADC Oversampling

    Part Number: TIDM-02000 Other Parts Discussed in Thread: TIDM-BIDIR-400-12 Hi, I'm investigating implementation of PSFB topologies . 1) I read some documents and investigating related software. I see that LV output is sampled differently at different…

  • TIDM-02000: CMPPSS RampGenerator, Resetting Ramp

    Part Number: TIDM-02000 Hi, I'm working on F280048. I'm investigating software of each PCMC phase shifted full bridge topologies. I'm implementing RAMP generator. Below is configuration for usage of internal CMPSS with Ramp generator. I generate…

  • TIDM-02000: TIDM-02000

    Part Number: TIDM-02000 Hi, When using the C2000 in peak current mode control, is there a formula to determine the accuracy or resolution of the main output of the power supply based on DAC slope compensator and PWM frequency? In another word, what is…

  • RE: TIDM-02000: Delays when Event Based Phase Shifting Operation in PSFB topology

    Resolved
    Hi Gus, Thank you for answers. Gus Martinez said: That would lead me to believe that there should be a difference of at least 3 TBCLK cycles. A difference of 60ns would make sense if your TBCLK was configured for 50MHz. However, in your description and…

  • RE: TIDM-02000: When should PCMC CMPPS Ramp Max value be set?

    Hi Ashwin, Sorry for the late reply due to holiday and other staff. Ashwin Ramanujam said: Shouldn't it be 65536? It should be 65536. I think we have fixed it in our latest solution. Ashwin Ramanujam said: Are there any references for PCMC with output…
