5-11. (Inrush Current)

Supporting the capacitive load of the power supply at startup and the sudden load access test
during operation to verify the current when the appliance is turned on and when the appliance is
suddenly connected, Is the Inverter output voltage transient response stable, as shown in
Figure 5-8 and 5-9.
