3.2 Performance Data and Results

The following waveform shows the TPSI31Px-Q1 EVM precharging a 2mF capacitor to 800V in 830ms. The charge time is slower than intended due to the inductor current saturation and the inductance derating, resulting in lower average charging current (2.26AAVG → 1.93AAVG).
