Both the CSV files, including bench bode plot test and Simplis simulation bode plot can be copied into one CSV file to do correlation. Figure 3-6 is the bode plot gain and phase margin correlation waveforms.
As previously shown, the bode plot correlation of simplis simulation vs. bench test are not very good, the LC double-pole frequencies (peak point) are not well matched. This may be due to the L values in Table 2-2 are not actual values. Considering 15% inductance detaining (0.578uH), the Simplis bode plot is updated in Figure 3-7, which matches the bench result better.
