Here is the original publication: http://radiokot.ru/circuit/power/converter/19/
Original discussion: http://www.radiokot.ru/forum/viewtopic.php?t=28822 (you may use Google Translate from Russian although it’s far from perfect in this case)
(Note that some annotations on the diagram at the top of this page are in Russian, it’s because the original scheme “made in Russia” :))

Main disadvantage of such schematics is a huge low-frequency transformer, main advantage is a reliability (provided the device is developed correctly).

I am from AUSTRIA, please excuse my English.
3 questions: 1. HIP 6601 is difficult to buy, are other IC’s usable?
2. I have troubles to define a detail in the circuit drawing, are R22 and R24 variable resistors with connection to the ground ( Connection R22/R23 respectively R24/R25)?
3. What is the purpose of the a.m. variable resistors?

Thanks

Can this be changed to output 120 VAC at 60 hz eaisily without having to redesign the whole thing? Also can more mosfets be added for larger output rating? thanks
