My new best pal Ben of BenandAmber fame has sent me a care package of nice parts. Included is a Nanoverter board, revision D. I need a little guidance to move forward with this. Not all of the components are populated. As I understand it, they may not all be necessary. I would like to verify what is and is not necessary to control an inverter with no mains sync. If there is a "Getting Started with Nanoverter" guide, I haven't been able to find it. All help is appreciated. Anthony |

Great to hear from you Ben! I have been knee deep in the old posts for quite a while now. I am amazed at the depth of it all. Personally, I'm not looking for anyone to tell me the answers, but if anyone knows the names of threads where the info has been hashed before, I'd be grateful. |

Just finished putting a small fet test board together. Those mosfets are rated at 95 amps, but I don't know how big of a heatsink I can get on there. We'll see. I only had 7 cm x 9 cm perf board, so I didn't have room for the opto isolators I want to use. I'll put those on another board that plugs into this one. The totem pole driver is made from 2n2222/2n2907 complementary BJTs. More to come!  |

I had so little room on the small board that I had to put the primary output on the under side... Don't judge me!  |

Had a little time to get on to this forum. I don't know if this is still needed. Crossed out components are not needed for dual nano basic operation. It was a long time ago, so this is what I remember, I hope others will check for errors. See attached pdf NANOVERTER_D_Base.pdf |

Tinyt: the pdf is correct. put the jumper on sync disable to ensure it stays LOW. And if you will not be using SCR OC shutdown, which I don't, no need for the below.  wronger than a phone book full of wrong phone numbers |

Hey thanks tinyt and Peter! I've just today gotten a Nanoverter into a condition to output power. It is an utter mess, but it works. I only have a 20 volt power supply on the bench, but it performs nicely with the limits of that source. The 60 Hz sine wave is rock solid except when I push the VFB all the way up. I have to back off of max a couple of turns on the pot else a strange ripple choices through the sine wave. But that's OK, because I was just testing the limits. I'll get some better pics when it isn't live and I take it apart.    |
