If one has designed an offline 230VAC, SMPS based LED driver whose power is 150W maximum, then as you know, one has to design a mains input filter to allow it to pass mains conducted emissions at 150W.
However, one then finds that this relatively highly attenuative filter prevents the converter from being able to pass mains harmonic regulations when it is dimmed down to 25W.
Do you know if the EMC regulations (mains harmonics regs) of the EU and the USA have allowances for this? (ie excuses for 25W operation of a 150W rated LED driver)
