Pump

The pumps which have been tested are rated for 120 V, 700 mA, 60 Hz operation. They

withstand the high voltage of the generator up to 6 kV, without flashing.

Figure 4 shows the behavior of an ACS with this load. During the breakover of the devices, a

capacitive current flows through the parasitic capacitor of the load due to the high dV/dt rate

applied to it. This current can reach up to 2 A. As the current pulse lasts around 100 ns,

there is no thermal issue. ACSs can withstand such a stress without any damage.
