3.2.2 Setup for Hardware and Software Validation

With the setup developed, the hardware and software can be validated in a low-voltage environment. The following hardware is required:

The hardware setup is illustrated in Figure 3-1.

  • One TIDA-010231 board
  • C2000 controlCARD TMDSCNCD280049C
  • DC power supply to provide 8-V to 16-V auxiliary supply to J2. Limit the current to 0.5 A. Refer to Figure 3-1 for polarity.
  • Function generator to provide a sinusoidal signal to the CH1 input J4 with variable frequency up to 100 kHz
  • Oscilloscope to observe waveforms at the filter test points
  • PC with Code Composer Studio software to observe sampled waveforms and the output of the arc detection algorithm.

The software project can be imported directly from the DigitalPower SDK into the Code Composer Studio IDE. (internal ADC software).

Detailed instructions on how to control the software are found in the User's Guide PDF document included in the downloaded package.
