AC DC Converters

1. Overview

AC-DC converters are electronic devices that convert alternating current (AC) to direct current (DC). They are critical components in power supply systems for modern electronics, enabling equipment to operate safely and efficiently. External/internal (off-board) converters are designed for integration into systems or as standalone units, serving diverse applications from consumer electronics to industrial machinery. Their importance lies in ensuring stable power delivery, voltage regulation, and compliance with global energy standards.

2. Main Types and Functional Classification

Type	Functional Features	Application Examples
External AC Adapters	Plug-in power supplies with universal input (90-264V AC), isolated output, and over-current protection	Laptop chargers, LED monitors, medical devices
Internal Board-Mounted Converters	Compact designs with high power density, designed for PCB integration with minimal external components	Servers, telecommunications equipment, test instruments
Open-Frame Converters	Exposed PCB design for optimal thermal management, requiring external enclosure	Industrial automation systems, power distribution units
Rack-Mount Converters	Modular units with standardized dimensions for data center scalability	Telecom infrastructure, cloud computing servers
