    با قطعات الکترونیکی ساده و ارزان مدار حذف باتری بسازید

    در این ساختنی آموزش ساخت مدار حذف باتری را یاد می*گیرید که می*تواند در مدارات الکترونیکی بجای باتری*های ۹ ولتی کتابی استفاده بشود. از این مدار می*توانید برای تغذیه هر نوع دستگاهی که با جریان ۹ ولتی کار می*کند، استفاده کنید. ترانسفورماتور T1 ولتاژ اصلی را پایین می*آورد و پل دیودی D1 کار یکسوسازی را انجام می*دهد. مقاومت C1 فیلتر و تراشه آی سی LM317T هم رگولاتور یا تنظیم کننده ولتاژ مدار است. مقادیر مقاومت*های R1، R2 و R3 طوری انتخاب شده اند که ولتاژ خروجی IC1 9 ولت پایدار و ثابت باشد. با ساختنی همراه باشید.
    دیاگرام مدار حذف باتری

    شماتیک مدار حذف باتری برای ساخت مدار حذف باتری نیازی به دانش زیادی از الکترونیک ندارید و می*توانید با استفاده از نقشه شماتیک بالا این مدار را به سادگی بسازید.


    نکات مهم در ساخت مدار:

    • مدار را روی یک برد مدار چاپی با کیفیت مونتاژ کنید.
    • ترانسفورماتور T1 می*تواند ۳۲۰ ولت اولیه، ۹ ولت ثانویه و ترانسفورماتور ۱٫۵ آمپر استپ داون (کاهنده) باشد.
    • اگر پل ۱A در دسترس نبود، خودتان با چهار دیود ۱N 4007 یکی بسازید.
    • قطعاتی که بیشتر از ۱٫۵ آمپر مصرف دارند را به مدار حذف باتری وصل نکنید.
    • بهتر است برای قطعه IC1 از یک هیت سینک استفاده کنید.
