TMS320F280039C: CLB configuration

Angela Zou
Intellectual 1085 points

Part Number: TMS320F280039C
Other Parts Discussed in Thread: SYSCONFIG

Tool/software:

Dear expert,

My customer's application is 5500W full-bridge LLC. The primary side is driven by the EPWM1 ​​module output, and the secondary side synchronous rectification is driven by the EPWM4 module output.
Due to the complexity of the CLB module, there are no comprehensive reference examples for configuring the relevant CLB registers using syscfg. Existing reference materials are overly simplistic and provide little help in configuring the CLB registers.
I would appreciate if you could provide detailed configuration steps to implement the relevant functions (e.g., how to enable ADC-triggered EPWM upper-side shutdown, how to copy the EPWM upper-side waveform to the EPWM bottom-side waveform, how to copy the primary-side EPWM waveform to the secondary synchronous rectification EPWM, and how to limit the turn-on time of secondary synchronous rectification EPWM).

    Hi Angela,

    We may not have a reference design that matches this exact CLB scenario but I can guide you with implementing these functions yourself, if CLB is required for these. I would suggest consulting C2000 academy for an introduction to CLB and the CLB tool user's guide to get familiar with using SysConfig to configure the CLB.

    Thank you,

    Luke
