Average
Figure 8.7.1. Vin=230Vac, full load, power supply floating.
Figure 8.7.2. Vin=230Vac, full load, power supply placed
on a plane (1.4mm insulation PCB) grounded via artificial hand.
The test set up, Figure 8.7.3., simulates the application, where the power supply unit (PSU)
is placed in a metal enclosure.
