New to this forum, main hobbies are welding and diy work.
My chinese milling machine has a toasted bldc card, so i'm building a new one with quality components.
I googled a lot, and really didn't find the right component, and also right way to connect it.
This is to protect igbt module from brushless dc overvoltage.....
Power: 1500 W V bus : 340 V I rated: 4,7A
SMD value for choke is 680 µ H
I only want discrete component, not SMD
Are following components right for the job?
See links and datasheet.
And also , how to connect these chokes?
If i decrease L value, say to 100µF , how igbt will work....
From phase to phase, phase to ground, or ?
Thanks a lot.
