Hello everyone;
I found this forum while looking for information on home made CDI. I want to thank those who have done so much work and for sharing. I would like to join in the development work with the LT3750 and am ordering it along with the DCT20EFD transformer made by TDK which is available from the local supply. I am surprised you guys can run a CDI from batteries as I did the scratch pad calculation to reveal that with 80mJ spark at 12000 rpm that means 16 watts if the efficiency is 100% so it must require around 20 watts from the battery. This is no small power and I am wondering if your engines have a generator??
