EN55015 for the light dimmer application
A CLC input filter is used to guarantee this standard. The filtering capacitors C7 and C9
each have the value of 100 nF (~275 V
(see
The load is 100 W and it consists of two lamps (40 and 60 W). The load is connected on the
board, which means the phase and the neutral lines are available for the power supply
circuit (see
the TRIAC, there are many states available for testing, but only the worst case (highest
noise) measurement is provided. This occurs when the TRIAC is turned on in the maximum
voltage of the sinusoidal waveform. Two measurements are required by this standard:
●
●
Both of the actual waveforms are under the requested limits, proving that this type of EMI
filter is suitable for the light dimmer application.
