 Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me. |

This will be bit of entertainment that can be read when a quiet moment is found. I have been reading about these inverter things and trying to get my head around how you do get something hefty going. As I was suddenly having to getup to speed doing some electronics work I thought it might be and idea to use Madness project because as some stage I thought I read he was not doing schematics, I thought it was all in his head and in his layout program of course. I am going to approach if from my point of view to try and understand what happens. I have not read enough here in the 'high' power section of the Forum so I do not know the story behind most of what goes on as well I do not remember too well these days either. I do feel more comfortable in 24V and down areas but the solar power has me interest. From what I gather now, oztules have provided inverter design that madness is following but with his own designs added. My apologies if I have got wrong. Ok, I started out with the slip that madness posted and I have studied the drawing oztules posted where tinyt made a very easy drawing to read. I am attaching a pdf files where I have drawn up the H bridge driving into big caps. We will see where it gets. No real values have been attached to the symbols yet so it is of no use at this stage. It does have one advantage, this file should read very nicely when blown up 1000% or more. Good for wall papering? 2018-05-21_222244_180521-oztooles-madness-1x-copy-problem.pdf |

I'm not particularly keen on that layout, too confusing for me. I prefer to have the inputs (all 4) on the left side and the output transformer, etc. on the right side. Klaus |

I like tinyt's... it is a virtual schematic of my board layout.. so very easy to cross check things.... I like easy  .........oztules Village idiot...or... just another hack out of his depth |

Just an update, things did not turn out as I expected. I did take a knock but am getting above water again. I thought I was having AutoTrax under control, at least to make some schematics. Well the heavens caved in, first I discovered that there may be a problem with AutoTrax when copying large areas, while trying to get that sorted out, the computer turned on me, I panicked and made bigger mess. Starting to wonder what on earth I had taken on. I have a 2GB hard drive waiting to be resurrected, and I thought all my DEX work was on that but turned out not to be the case. I have recovered most of my DEX work and I think including what I started here. I am on better terms with my computer and will soon be starting doing schematics again and I hope to progress a bit further here just for the exercise, I can do with that. |

I use Google drive for all my documents, photos etc. I have everything on my own computer and every file that goes into the directory is uploaded to the cloud. So long as I can log into the Internet I can get any file. Computers can and do go wrong, they also could be lost in a fire or stolen. There is also the possibility of a ransomware attack, I think my files are safer on Googles server than they are in my house. There are only 10 types of people in the world: those who understand binary, and those who don't. |

Madness I think I should consider the use of the cloud, for certain things, partition tables would be one. I do however prefer my own hard drives, but as you have pointed out this can be risk too, what I fear most is a 'real drive' break down, have had some, very few but of of course it happens. For me I more often mangle the formatting of hard drives, being a bit too enthusiastic like when I managed to stuff up my 2TB drive when doing DEX investigation on VM machines. Somebody in the linux world scared me enough, he doubted I knew what I was doing well there is a point there , at least get another drive and make a copy before starting first aid on the partition table. So I have done the right thing and the drive will be here this week. I expect to recover about 1000GB, bit painful with these big drives, they can hold so much.A little DEX experimentation, adding the internals of a switch mode power supply IC to the part, so that in the schematic my failing memory has a reminder to what is inside as block schematic. Sounded like a good idea but did not work yet, following up on the DEX forum hoping for positive outcome. Here is a picture of what I am doing:  Keep in mind, the schematic can be fanciful to degree, I can build a circuit around this as the pin outs are correct and block schema will make for easy reading, the printed circuit board in due time will not care about this presentation, the foot print will be right. |
