TMS320F2800157: Trip zone

Hello Brian,

First, I'd recommend going through the device TRM section 14.9, 'Trip-Zone (TZ) Submodule', which describes the functionality and use of the TZ. I'd also recommend going through the C2000 Academy., which provides a fantastic training on using the C2000 peripherals, including the ePWM (5. 'Control Peripherals' -> 'Enhanced Pulse Width Modulation (ePWM)').

Then, for practical implementation, please see the driverlib examples for the ePWM, particularly the following examples:

• epwm_ex1_trip_zone
• epwm_ex4_digital_compare
• epwm_ex5_digital_compare_event_filter
• epwm_ex7_edge_filter

Example 1 provides an example of TZ usage, while the other 3 provide examples on using the Digital Compare (DC) Submodule, which ties very closely to the TZ. The 'epwm_ex6_valley_switching' example may also be useful for digital power applications requiring valley switching.

Jason Osborn
