Power conversion is essential in modern electronics, and two of the most widely used technologies are AC-DC and DC-DC power supplies. Understanding the difference between these solutions helps engineers and purchasing teams select the right product for their applications.
AC-DC power supplies convert alternating current (AC) from utility power sources into direct current (DC) used by electronic equipment. These power supplies are commonly found in industrial automation, medical equipment, telecommunications systems, and consumer electronics. Their primary role is to provide stable and regulated DC output from standard wall or industrial power inputs.
