Application Circuit
4.1
Results of THD Measurements with Application Board P_out = 110 W
(Measurements according to IEC61000-3-2.
150% limit (red line): Momentary measured value must be below this limit.
100% limit (blue line): Average of measured values must be below this limit.
The worst measured momentary value is shown in the diagrams.)
