Fluorescent lamp inverters


The replacement of incandescent lamps with fluorescent lamps is being promoted as a great way to reduce CO2 emissions. Consequently, the importance of fluorescent lighting is increasing and the use of inverter-controlled fluorescent lamps is becoming widespread due to their emissions efficiency. To create a highly efficient ballast lighting control system, we recommend the use of an 8-bit microcontroller capable of half-bridge and PFC control for lighting purposes - and a power MOSFET.
This combination also supports communication control by means of a digital addressable lighting interface(DALI).
