measurement points.
6.2.2 Short Circuit II (high inductance)
An inductance between the power terminal of the phase output and the DCL+ terminal was inserted for the
short circuit II tests. A current probe measures again the currents of this short circuit (IL). The equivalent
circuit during this test is shown in Figure 24.
