مبدل DC-DC یا به اصطلاح DC-DC converter مبدلی است که جریان DC یک منبع را از یک سطح ولتاژ به سطح ولتاژی دیگر تبدیل میکند و ولتاژ خروجی میتواند از ولتاژ ورودی بیشتر یا کمتر باشد. مبدل Buck نوعی
مبدل DC-DC کاهنده است. از این مبدل برای کنترل سرعت موتورهای DC استفاده میشود. ماژول رگولاتور کاهنده مدل XL4016 در ابعاد 80x53x35 میلی متر و با کیفیت ساخت عالی و بدنه ی مقاوم و مستحکم ساخته شده است. این ماژول رگولاتور کاهنده دارای ولتاژ ورودی 7 تا 36 ولت و ولتاژ خروجی 1.5 تا 32 ولت می باشد و از جریان خروجی حداکثر 10 آمپر برخوردار است اما پیشنهاد می گردد برای عملکرد بهتر این ماژول جریان خروجی 8 آمپر گرفته شود.
برای عملکرد بهتر ماژول توصیه می گردد که فن روی آن نصب شود تا گرمای ایجاد شده باعث کاهش بازدهی و طول عمر ماژول نشود. ماژول رگولاتور کاهنده با فرکانس 300 کیلوهرتز دارای راندمان تبدیل تا 95 درصد می باشد.
تفاوت عمده این
ماژول رگولاتور کاهنده ولتاژ، وجود صفحه نمایش برای میزان تغییرات ولتاژ و جریان با دقت 0.01 ولت و 0.01 آمپر بر روی صفحه نمایش سه رقمی است. لازم به ذکر است این ماژول دارای قابلیت کالیبره شدن می باشد تا خطای نمایش را به حداقل برساند.
Description:
Converting a higher DC voltage to a lower one is a common requirement found in most electronic circuits. This might be something like converting the 12V from a battery down to 5V in order to power an electronic board. A portion of that 5V may be further converted down to 3.3V to drive a lower voltage portion of the circuit. It is a class of switched-mode power supply (SMPS) typically containing at least two semiconductors (a diode and a transistor, although modern buck converters frequently replace the diode with a second transistor used for synchronous rectification) and at least one energy storage element, a capacitor, inductor, or the two in combination.
DC-DC step-down converters basically take a higher input voltage and convert it to a lower output voltage by chopping it up by rapidly switching the output power transistor on and off so that the output essentially looks like a square wave and then using an LC filter to smooth it back into a DC voltage on the output of the filter. DC-DC converters are inherently electrically noisy devices. Its job is to basically take a nice calm flat DC voltage and violently chop it up into pieces and then smooth the pieces back out into a DC voltage again using an output filter. That output filter consists primarily of the inductor and capacitors in the output circuit and depends heavily on the board layout to optimize the quality of the filter.
