10.3 Drain Voltage and Current Start-Up Profile
Drain Voltage and Current waveforms are presented with the simulated battery load.
Figure 17 – 90 VAC Input and Maximum Load.
At start-up with a battery load, Drain current and Drain voltages are well controlled and
within acceptable operating limits. Note that the peak of the I
is the leading edge current spike not I
