Haxby, yes. In a previous post I mentioned the supply and I wanted to have the choice of 0 - 12V and -12V to 12V, controlled by a 3 pin jumper. I can not resist the chance to do a near optimal comparison of this 2.
Warp, I will still use my nanoverter and the IR2184(4). It's a $6 part that gives me the 500nS deadtime. I think I could arrange so that the new design is pin for pin compatible with the previous boards with the 10 pin IDC socket. This will make testing and comparison heaps of fun for me.
I think I connect IR2184 VS pin to low side DC ground, VB pin to 12V+ and HO will be DC ground referenced signal of 12V, just like LO. The connections will occur on the powerboard.
Brownout and startup conditions have to be studied before I can comment. I agree time has to be spent looking at this stuff. Edited 2021-05-02 18:34 by poida |
