AC AC Wall Adapters

1. Overview

AC AC Wall Adapters are external or internal power conversion devices that transform alternating current (AC) from mains outlets into regulated AC or DC output for electronic equipment. These adapters serve as critical power interface solutions in consumer electronics, industrial machinery, and medical devices. Their importance stems from enabling safe voltage conversion, electrical isolation, and compliance with global safety standards.

2. Main Types & Functional Classification

Type	Mounting Style	Output Type	Key Features	Applications
External Adapters	Wall-mounted	AC/DC	Plug-and-play, field replaceable	Smartphones, Laptops
Internal Adapters	Chassis-mounted	AC/AC	Integrated circuit protection	Medical equipment, Servers
Universal Adapters	Modular	Multivoltage	Adjustable output, interchangeable tips	Travel electronics

3. Structure & Components

Typical construction includes:

Fire-retardant housing (UL94-V0 rated)
Transformer assembly (EE/I-core or toroidal)
Rectifier bridge with filter capacitors
Switching regulator (PWM controller)
Protection circuits (OVP/OCP/SCP)
EMI/RFI filtering stage

4. Key Technical Specifications

Parameter	Typical Range	Importance
Input Voltage	90-264V AC	Global compatibility
