  • مبدلهای DC/DC 

مبدلهای DC-DC وسیله‌های الكترونیكی هستند كه هنگامیكه ما می‌خواهیم برای كارایی بهتر نیرو الكترونیكی DC V را از یك سطح ولتاژ به سطح ولتاژ دیگری تغییر دهیم استفاده می‌شوند (كاربرد دارند). ما به این مبدلها احتیاج داریم چون بر عكس Ac، سیستم DC به سادگی نمی‌تواند بوسیله یك ترانسفورماتور افزایش یا كاهش یابد. در بسیاری از روش‌ها یك مبدل DC-DC معادل DC یك ترانسفورماتور است. نمونه درخواست‌های مبدل‌‌های DC-DC جاهایی هستند كه DC 24V را از یك باتری كامیون باید به 12VDC كاهش دهیم تا یك رادیو ماشین را به كار اندازیم و ترانسیور CB یا موبایل جایی كه 12VDC از یك باتری ماشین باید 3VDC كاهش یابد تا یك DC plyer شخصی را به راه اندازیم؛ و جایی كه 5vDC روی یك كامپیوتر شخصی (مادر برد) باید به 2V یا 3 یا كمتر برای یكی از آخرین (جدیدترین) تراشه‌های CPV كاهش یابد؛جایی كه 340VDC بوسیله مبدل برق AC240V بدست می‌آید باید به 12V, 5V و دیگر ولتاژهای DC بعنوان قسمتی از منبع pc كاهش یابد بخش از DC-AC معكوس كننده و جایی كه 1.5v از یك سلول ساده باید به 5v یا بیشتر افزایش یابد تا بكار اندازیم مدارات الكتریكی جایی كه 6v یا DC9v باید افزایش یابد

Here is where I put all of my expired web 2.0 accounts.
I scrape massive lists and then check to see if they’re expired.
I think you’ll be surprised by the number of accounts that I come across.
Hopefully, you’ll be able to put these expired accounts
to good use.

I would like to thank you for the efforts you have put in writing this website. I’m hoping the same high-grade site post from you in the upcoming as well. Actually your creative writing abilities has encouraged me to get my own website now. Actually the blogging is spreading its wings quickly. Your write up is a good example of it.

Hey there! Do you know if they make any plugins to safeguard against hackers? I'm kinda paranoid about losing everything I've worked hard on. Any recommendations?

I don't know if it's just me or if everybody else experiencing issues with your website. It appears like some of the text in your posts are running off the screen. Can somebody else please comment and let me know if this is happening to them as well? This might be a problem with my browser because I've had this happen before. Many thanks

fantastic submit, very informative. I wonder why the
other specialists of this sector don't notice this.
You must proceed your writing. I'm confident,
you have a huge readers' base already!

The article is worth reading, I like it very much. I will keep your new articles.
پنجشنبه 17 آبان 1397 09:55 ق.ظ
Have you ever thought about writing an e-book or guest authoring on other websites? I have a blog centered on the same information you discuss and would really like to have you share some stories/information. I know my viewers would value your work. If you're even remotely interested, feel free to shoot me an email.
چهارشنبه 16 آبان 1397 09:01 ق.ظ
I believe everything published was very reasonable. However, what about
this? suppose you composed a catchier title?
I am not saying your content is not good, but what if you added a post title that makes people want more?
I mean ایران مقاله - مبدلهای DC/DC is a little boring.
You might peek at Yahoo's home page and see how they create article titles to get people to click.
You might try adding a video or a picture or two to get readers excited about what you've got to say.
In my opinion, it would bring your posts a little livelier.
