Hi all!
A friend of mine has this Nokia gadget that has 8 digital outputs that can put out 6-30 VDC. I was asked to help design and build a circuit/s to turn each output into 220-240 VAC to make 8 outputs, each capable of supplying a 500 Watt device. I've been looking at inverting circuits (like these: https://electronics-diy.com/electronic_schematic.php?id=605 , https://electronics-diy.com/electronic_schematic.php?id=655)--some outputs can be 100-200W...and done some price calculating and 8 separate inverter circuits would cost a great deal. I dont suppose there is any way around this since each 6-30V output needs to trigger a separate device (but if anyone knows of a cheaper solution or at least cheaper "inverter" circuits help would be appreciated). Basically, the thing I really need to ask is if each DC output gives 6-30V what kind of circuit would I need to design or look for that could take this variable input voltage and put out a steady 220VAC? Thanks!
