What is AC/DC power supply?

AC is the abbreviation of alternating current, DC is the abbreviation of direct current.

AC / DC power supply, a ac input and dc output led transformer. For example, the phone charger, laptop, tablet computer power adapter we used are ac to dc power supply.

Inside this power supply contains a step-down circuit, rectifier filter circuit, and voltage regulator circuit. In the application of AC / DC power supply conversion, require a wide input range, usually 85V ~ 265V AC input voltage, high output power conversion efficiency , and can improve energy efficiency greatly. Full load efficiency Is a major consideration in the AC / DC power supply designing. Improving the efficiency of AC / DC power supply to achieve better energy-saving performance, is the green energy advocacy nowadays.
