Hi guys,
Has someone here experience with electronical Ballasts for HQI Lamps?
Because i built one, but i have some problems:
First the lamp wasnt able to start, it was flaring at 50Hz (i guess)
Then i added a capacitor after the rectifier, it was flaring lesser but still flaring,
then i changed the Mosfet (first i used k2387) to irf740, now its working, but if i shut down the circuit
and try to restart when the lamp is hot the Mosfet are exploding. If ir remove the main capacitor they stay alive, but the lamp is flaring
and wont start. can someone Help me?
The schematic i use is from this site:
