    All oscillcospe codes in main.c.

    Create project with cubemx "oscilocpe.ioc"

    Must copy main.c to project driectory.

    Because for small rar file size.

    Cubemx project is full of junk files.

    Thanks.

    I am interested in electronics as hobby.

    If I work gently, it will be torture, not entertainment.

    This device (plasma cut) is very expensive in my country. 3 minimum wage.

    İf transformer 16v not need regulator, if transformer 24v 18v yes you must use.

    For the gate voltage, mosfet or igbt gate voltage must be min 11V --- max 20v.

    Maybe not, very small signal and maybe 500-600v



    1W to more KW , It depends sound frequency and out capcacitor.

    Sound interupt frequency must 1HZ to 1-2khz

    As the frequency increases,...
