Couple of things to watch out for. Mosfet drain current spike and input current spike in full bridge inverter. I think I came up with a pretty slick way to mount my 5V regulator and MOSFET to the upper board ucc377322 makes everything very compact and tidy and lets them connect to a common heat sink. I appreciate any help or guidance – I’m sure the answers to 1 and 2 are in uxc37322 documents I’ve been through, I’m just not seeing them.

So, I shall plug on ahead and see how it goes. Started by rashan shrestha 31 minutes ago Replies: The answer to 3 is in wisdom that I do not yet possess.
Input voltage could be either 12V or 24V, and the nature of the load to be driven is unknown – could be inductive or resistive. Even though your mosfet is rated at 75a, that is steady state and in lab conditionsin a switching application the mosfet will spend some time in the linear state while it is switching, using the driver reduces this however you need ta take that into account when working out dissipation.
I’m a mechanical engineer, so this is way outside my wheel house!
Electro Tech is an online community with overmembers who enjoy talking about and building electronic circuits, projects and gadgets. Thread starter MikahB Start date Apr 26, Both boards are about 2″ x 2. I think I could slow it down – at least on the rise – without any real impact on the functionality of my output.

TI Debuts UCC/UCC MOSFET Drivers –
And just for the record, I am all about hands-on other than the seemingly endless hours I spend reading datasheets and white papers trying to understand this stuff.
Playstation 1 motherboard housing fell off, help! I’m just trying to make sure I understand what’s what and I’ve found that me not asking often equals me misunderstanding. MikahB New Member Apr 26, I will proceed with working towards making my ucd37322 functional prototypes and hopefully that will help me determine if EMI is a problem or not.
I think I will be okay on heat dissipation as the heatsink is large, but thank you for the information. Another one I found when using mosfet drivers was that the waveform from the output of the fet was so square I was getting loads of harmonics and rf interference. I’ll do some research on harmonics and RF and see what I should be looking at.

I’m using an Allegro AC current sensor to monitor current and limit it via duty cycle to 30A for now. Thanks again for the info. Articles Top Articles Search resources.
