In Table 2 the percentage variations (device B vs. device A) of the measured parameters are

reported and defined as:

As shown in Figure 12 and Table 2, device B shows higher values for almost all measured

parameters; in particular, the gap becomes wide for maximum peak, average values at turn-

on and off and maintenance current.
