    I was wondering if anyone can provide me with comprehensive information regarding the construction of an inverter from start to finish. I would like to use it in an induction heater, so it should be able to handle anything from 2 kw and up. Furthermore, I am rectifying mains ac to dc and using a smoothing capacitor,thus the input voltage is above 220 volts. I would, therefore, also like to know if i should first step down this voltage then convert to dc? Also, doesn't the inverter step up the low input dc(after being converted to ac) voltages as those you get from car batterries, so was wondering that this high input current would not necessitate stepping up voltage?N.B i appreciate the time taken to read and consider answering, but please do not reply by saying not enough info, if you feel there is anything left out, please answer with that taken into consideration.

    Much apprecation

    We don't have full blown engineers waiting to teach you a college level course and design inverters from scratch for you.

    So we are to hand over our custom-designed inverter for you, but we don't get to ask questions?


    Here's my solution:
    Connect...... PWM....sine....90° phase shift .... bear.... honey.... large amount of glue.....unreasonably large pickle...... 2kW inverter!

    If you feel there is anything left out, please build with that taken into consideration.:D

    Before writing posts, think of handing over your papers in a job fair.

    Would you attach a weird party photo with a supposed to be appreciated comical gesture?

    Or also drink a Red Bull, throw the can over your shoulder and burp.

    Your post is like that.

    There is a complete inverter design in there somewhere, if I can find it:

    Firstly i apologise for offending anyone, it was not my intention. I just wanted info on how to build a decent inverter to make a high powered induction heater. if anyone can help?

    for example here is a good page http://danyk.wz.cz/induk3_en.html also try googling induction heater schematic to get other results.
    How much experience do you have in electronics?

    So why are you rectifying AC? Why not use the AC that is available?

    Here is some information on inverter design:

    thanks, the info was very useful.going to read over it and try to understand it.I have a very basic understanding of electronics.I cannot use mains ac because it is only 50 hz and i have read that the induction heater needs high frequency ac.
