Is there any way to make CDI (capacitor discharge ignition) using power mosferts,I`ve searched on google but it only shows using SCR

 

Hello,

Have a look at the following PDF in the link:

You need to have an oscillator to make the HV, and a capacitor to store it, most cdi's use a Thyristor to fire the capacitor across the coil, it's the best method as it turns itself off when the capacitor is discharged ready for the next trigger pulse.

 

Why do you want to use a MOSFET?
It has no significant advantage over an SCR, and has some disadvantages.

because I can`t find a SCR and a Have a lot of mosfets
