So can a mechanical (lamp) produce energy at a frequency lower than its being driven at.?
PWM less than 5% doesnt really work for halogens, I think they only start to give a shimmer of light at about 20% if i remember correctly.
that the faster you turn on/off mosfet, the more EMI your wiring radiate.
The solution only to place mosfet as close to load(bulb) as possible
Quotethat the faster you turn on/off mosfet, the more EMI your wiring radiate.True but PWM of any ratio will turn the FET on at the same speed.
consequently EMI would be stronger for low PWM.
