10.2 Output Voltage Start-Up Profile, Battery Load
A simulated battery load was used to verify the power supply start-up profile.
Figure 15 – Battery Start-Up Profile, 90 VAC.
With a simulated battery load, the output voltage reaches regulation within 200 ms. No
output overshoot is observed. Note that the peak of the I
