Hi all, 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. jm Last edited by JM-M; 03-12-2011 at 05:12 AM.  |
