An inductor in series with a triac (which is in turn controlling a light bulb) will control the rate of current increase while wasting a minimum of power. Proper inductor design minimizes radiated energy, and the controlled rise time blocks noise (high harmonics) from propagating back into the power source.I have seen the example of the inductor with the light bulb that you speak of. What doesn't make sense is why you would want to create a magnetic field close to other circuitry. Won't that in itself create problems?
Thanks, MrAl. I have seen the example of the inductor with the light bulb that you speak of. What doesn't make sense is why you would want to create a magnetic field close to other circuitry. Won't that in itself create problems?
