    Yes, I have finally modified the mw104.zip (this appears to be a newer file). The corrected file is attached here:156537

    You need to unzip and upload the final.hex - fortunately the code was not...

    I have compiled the source file once again (the one named 020026-11.zip) and there appears to be no serious error (some warnings are there).

    Even peak voltage ratings have limits: it is never specified but may be +/-5%

    Exact nature of the damage is usually not specified. Some damages are cumulative but some may recover too with time.

    I shall take a look on the first set tomorrow and let you know. If that does not work, I shall work on the second file.

    It is not really difficult. I have edited hex files in younger days.

    [SOLVED]Closed: Re: Ohm's Law and Power calculation problem

    That is the point I am trying to convey: it is not possible to measure any quantity in ZERO time; all physical measurements take time to perform.



    No, it is still defined. Consider a sine wave...

    I am puzzled; I shall compile the original and send you once again. Without any modifications: that should tell whether I have made any mistakes in compilations.

    It need not be exactly zero; in floating point asthmatics, you test for zero with a small number.

    [SOLVED]Closed: Re: Ohm's Law and Power calculation problem

    What you have done is called point-wise division. This may not be same R(t)=U(t)/I(t) under some conditions. Particularly near singularities. I won't go into these details. Recall that division by...

    [SOLVED]Closed: Re: Ohm's Law and Power calculation problem

    Please explain: if you are using R(t)=U(t)/I(t) to calculate the resistance, I have no problem. But the 4th graph is misleading, because you are trying to plot a point where the R becomes infinite.

    I have made some changes (only partial). OZ2CPU has been replaced by REVE FM.

  16. Closed: Re: Scoping the post rectifier DC bus in a 240VAC , 100W PFC'd flyback

    If you do not mind a little heat, you can perhaps turn on (and off) the drive FET a little softly. Most of the noise (I am afraid) is coming from the hard turn on of the pass transistor. Perhaps if...

    There is a space present; remove the space and recompile. You cannot return a long int (i.e., result) as a regular int (in the two functions add and sub); the compiler may not grumble but the results...

    Looks tell a lot. This is not regular noise. All the noise is coming from the down side.



    And that may be the cause of the untimely passing away of the filter caps (sooner than later)

    The files are very old and the compilers have become more strict; that is the reason the program is not compiling.

    This is only "apparently" correct because "shifts" are essentially multiplications or divisions by 2. And if you think in terms of binary system, multiplications are nothing but shifts and additions...
