Experimental results

In this section the characterization of the circuit is given. Four load conditions have been

considered:

1.

Output1 = open load - output2 = open load

2.

Output1 = full load - output2 = open load

3.

Output1 = open load - output2 = full load

4.

Output1 = full load - output2 = full load

In Table 3 and Table 4 the experimental results are listed, with 80 V and 285 V input voltage

respectively. In all the considered operating conditions the proposed power supply meets

the given specifications. The efficiency has been evaluated and is shown in Figure 6, where
