    Please I need someone to help me with a circuit I can use to supply a 26/28/115V 400Hz supply from 220V 50Hz. I need it for my school project. Thanks a million.:confused:

    The usual question. How much power do you need from these outputs?

    It would operate just like a switching power supply- 90 to 240 V AC 50-60Hz input with a 400Hz oscillator & thin steel lamination transformer. Sorry no ckts as this involves high V before the transformer [ bridge rectifier, MOV, fuse, & filter cap].

    Crutschow and Bernard, Thanks a lot for your reply. I would love to supply a load of 25amp. My supply will be from a 220V 50Hz generator. I'd seriously need help here because we dont do design in my school. I just want to do something new.

    Are you planning on building this?

    If so then this is not appropriate for a school project.

    Yes I want to build that. I may not go miniature. Hoping to achieve it using normal electronics (Transistors, capacitors, resistors...) and a transformer or so. To make any reasonable impact at times costs a lot. I am willing to give it a try. Can you asist?

    25A doesn't help with out knowing at which voltage it refers to- or did you mean 25 W ? Some speculation: If 700 W required, @ 60 Hz, core would be around 10 pounds, an audio or ferrite core then might 10 X 60 / 400 = 1.5 lb. Time for me to drop out as this is high V, & I have no experience building a hi V oscillator.
