Nice PWM. I just scored an old 5kVA UPS. Some comic took the control board out and no-one knows where it is. Your circuit has motivated me to repair the old thing. The centre-tapped transformer is still OK. For it to be a switching power supply is not THAT important at this stage. That can come later if I get further motivation. The DC side is 96V and it has taps for 220V (South African official voltage), and 250V(my voltage. I got the utility, ESKOM, to tap me up a bit….everything works a bit better).
I like your website btw. The Medieval characters make it very attractive. I work at a Medieval theme restaurant near Jo’burg (www.greensleeves.co.za). Funnily enough, the owner’s wife is Lebanese (born Haddad). Her mother was a Yasbek before getting married.
If there are any tricks over and above the explanations you give in going to 96V, please let me know.
Greetings from sunny South Africa.
Yes Haddad is a famous Lebanese family.
The inverter is posted on instructables.com, there are hundreds of useful questions answered by me there, I suggest you make a visit.
Thank you for passing by and the nice comment on the website 🙂
Hi Nick !
I saw your DC/AC inverter on instructables and i was wondering if you could be so kind and help me out in my DC / DC inverter design. It’s 72V in and 450V out and the transformer is already made for it. The power of this inverter should be in 5 – 8kw range. If you could please find some time i can explain you why i want to use/redesign your schematics and why i need your help.
Best regards !
May I ask for what purpose are you making this high voltage inverter? because like I said, motorized units are not recomended to run on this design.
This dc/dc converter should be connected to one 10kw 3phase motor controller.
This controller can accept 450 – 520VCD or 3phase input. I was planning to use this to power 3phase devices.
I know how to convert this into dc/dc but i will have some problems with my transformer and the design. Can i send you email ?
this is not a dc/dc converter, anyway yes email me to email@example.com
🙂 i know it is not. My plan is to convert it to dc/dc.
I have send you email.
