About DC-DC Power Supply suppliers

DC allows constant current to flow to the device. Since alternating current is initially provided, the power source must first be converted from alternating current to direct current. Most smaller electronic devices, such as computers, require DC power to work with AC-DC converters from wall power.

AC-DC Conversion Basics
يأخذ مصدر الطاقة طاقة التيار المتردد من مقبس الحائط ، ويحولها إلى طاقة تيار مستمر غير منظمة ، ويستخدم محول طاقة إدخال لتخفيض الجهد ، عادةً إلى الجهد المطلوب بواسطة الحمل. يفصل المحول أيضًا طاقة الخرج عن مدخلات التيار الكهربائي لأسباب تتعلق بالسلامة.

There are two types of AC power sources, unregulated and regulated. Unregulated power supplies are the most basic type of power supply and cannot provide a consistent voltage to the load, while regulated power supplies have and have many different design options.

Linear converters are the simplest, but also generate the most heat, while switching converters are more complex and cooler, but generate more noise. Batteries are usually switching converters. Each has advantages and disadvantages, but which one to use depends largely on the type of application and the conditions under which it is run.
