Hi!
I copied the DC-AC circuit from here, or specifically speaking this image (I didn't used the diodes because I think they are useless in described configuration). However when I observe AC voltage using DMM, I get the following results:
1. 5W LED bulb with capacitor shows voltage 37.4V
2. 5W LED bulb without capacitor shows voltage 46V
3. 9W LED bulb with capacitor shows voltage 65.9V
4. 9W LED bulb without capacitor shows voltage 99.6V
5. 30W LED bulbs without capacitor shows voltage 100V but LEDs start to flash
6. 30W LED bulbs with capacitor shows voltage 65.6V, LEDs don't flash but light is dim.
Operating Voltage (Desired) = 220V
Operating Frequency (Arduino Coded) = 60 Hz
Kindly tell me the reason of this behavior.
Kindly help me how in getting 220V stable AC output?
if there are any pre-built components that I can attach after transformer to stabilize it, kindly let me know about them too!!!
Thanks in advance!
