After a few seconds, the inrush relay clicks. The software is programmed to do so in the build level with DC. The trip clears, and a duty cycle of 0.5 is applied.
In the watch view, check if the guiVin, guiVbus, guiIi, variables are updating periodically. As no power is applied, this value is close to zero.
Slowly increase the input DC voltage from zero to 120 V. The output voltage shows a boosted voltage as a steady duty cycle of 0.5 PU is applied as the default setting. If a high current is drawn, verify if the voltage terminals are swapped. If true, reduce the voltage to zero first and correct the issue before resuming the test.
Verify the voltage sensing by ensuring that TTPLPFC_vBusAvg_pu displays the correct value. For 120-V DC input. This verifies the voltage sensing of the board in some manner.
The dutyPU_DC variable can be changed to see operation under various boost conditions. This verifies at a basic level the PWM driver and connection of hardware
Once finished, reduce the input voltage to zero and watch for the bus voltages to reduce down to zero.
This completes the check for this build. The following items are verified on successful completion of this build:
If any issues are observed, a careful inspection of the hardware may be required to eliminate any build issues and so forth.
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).
