Datawheet, to take a step back and answer the questions from earlier I am in fact using the IRF Bwhich is good to A derating notwithstandingper the datasheet, and comes in your usual TO package. At the time, the board was half the length of this board the MOSFETs were basically back to back with a slab of aluminum to pull the heat away sandwiched between themand I went with a star point because it was irrl4310 to run the driver line to the return line because everything was so close.

I cobbled that schematic together really quickly yesterday morning before I made the post. Spinner fishing steelhead salmon trends: I’m thinking about adding in some diodes in between the PIC outputs and the IRs to block any reverse current. Or something else I do a dwtasheet is only test one or two phases at a time by playing with the source code – this way you are reducing the amount of things you are trying out for the first time and all at once.
As irfl410 it killed 2 outputs lines on the PIC.

Help me debug my controller design Get all your technical information about electric bikes here. So again thanks for the catch, and I’ll be updating the schematic before I repost! All books are in clear copy here, and all files are secure so don’t worry about it. I’d still like to know what irfl410 flowing back into the controller though if in fact something is.
If so, you are going to be disappointed with the torque from your controller.

Thanks again for the feedback, and hopefully as this project matures, you’ll continue to chime in along the way! Regarding the star grounding on the low side of the MOSFET board, my original double sided PCB design did actually use a star configuration for the returns on the gate drivers.
Any feedback would be appreciated!
This is the most in depth writing about this subject that I have ever found. Fishing spinners slow in river current causes the blade to pulse and throb sending an irresistible vibration to trout, steelhead and salmon. The only difference being that I’ve modified the driver stage to use the IR Mosfet drivers. Thanks again for your help.
I can’t see why anything should happen if all the FETs are inactive when you plug the motor in and stay that way as they should. Do I have the right part? And if anyone has any other ideas as to what was going on, please chime in! After that, I plug in the MOSFET board, and apply 36V to it – but it isn’t plugged into the bike just yet, and it at this point, it seems that everything is still fine. Fishing spinners in a river or stream for trout and steelhead is not a subtle fishing technique that requires a strike indicator.
Shortly I’ll be posting details on the forum for anyone who might be interested to follow along.

Everything works as expected in that when I’ve got my hall sensors plugged into the PIC microcontroller, the right control lines toggle at the output pins iefl4310 the chip. Up to that point, I had just been going with hand drawn schematics, and when posting the question, I wanted to have something a little nicer to refer to.
Make sure the bootstrap diodes aren’t blown. I put in some diodes inline with the PIC outputs, and fired up the motor.
Spinner fishing for steelhead salmon and trout pdf I should have mentioned Next, I plug in the IR, as shown in the schematic, and again it behaves as you’d expect. Anyway, I’ve been making do with what I’ve got around the house for now.
Generally there are three types of rods used today graphite, fiberglass, and bamboo rodsIf searched for a book Spinner Fishing for Steelhead, Salmon, and Trout by Jed Davis in pdf format, then you have come on to the correct website. I’d have expected the IRs to act as datazheet buffer, but alas that doesn’t seem to be the case Your point is well taken, and I think the ground loop is likely what’s causing me so much grief.
I can’t see any reason the output lines on the PIC should die unless something is cross connected. Has anyone encountered anything like this before, or anyone have any insight as to what might be going on. Do you have a scope to check the signals to be sure?
