AN1894 - APPLICATION NOTE

Furthermore conducted emissions were measured in neutral and line wire using peak or average

detector. The measurements were performed at 230VAC input voltage and the 15V output was fully

loaded by 100mA load. The presented results depicted from Figure 18 to Figure 21 show the results. For

compliance with the EN 55014 standard, a small input filter (X-capacitor, common mode choke) should

be added, if there is no EMI filter for the complete system. Alternatively, a double sided pcb can be used.
