Hi Seniors,
I am new to this forum and I am designing an electronics circuit for 73 watt HID lamp. The lamp power is controlled with TRIAC. The spice model of my design is shown below in the first attachement. I can already control the current through lamp, but the the problem is the current waveform is not smooth enough. I mean the the current is rising suddenly to the maximum value as you can see in the following attachement 2 (dimmer), but I want that it would increase smoothly just just like a sine wave. My desired result is shown in the third attachement below.
I tried to go through all of the threads related to TRIAC, but I could not fine any solution for my problem. Could you please help me to modify my my circuit to get desired result.
I tried to explain the situation completely, but if you want to know something more about it please ask me, and I sorry if this is very low level question for you and for wasting your time.
Thank you in advance,
Sacha
