The inrush relay is closed when the DC bus voltage is higher than 110 V. The trip clears, and a sinusodal duty cycle is applied.
In the watch view, check if the TTPLPFC_ac_volRms_sensed_Volts, TTPLPFC_vBus_sensed_Volts, TTPLPFC_ac_curRms_sensed_Amps, variables are updating, periodically.
Note: As no power is applied right now, this value is close to zero.
Now slowly increase the input DC voltage from zero to 240 V.
Verifying the voltage sensing: Make sure TTPLPFC_ac_volRms_sensed_Volts and TTPLPFC_vBus_sensed_Volts display the correct values, for 240-V DC input, TTPLPFC_ac_volRms_sensed_Volts is close to 85V. This verifies the voltage sensing of the board in some manner.
Verifying the current sensing: Notice the TTPLPFC_ac_curRms_sensed_Amps for the given test condition; this value is close to 0.65 A.

The controller can now be halted, and the debug connection terminated.
Fully halting the MCU when in real-time mode is a two-step process. First halt the processor by using the Halt button on the toolbar () or by using Target → Halt. Then take the MCU out of real-time mode by clicking on . Finally, reset the MCU by clicking on .
Close CCS debug session by clicking on Terminate Debug Session (Target → Terminate all).
