AC DC Converters

1. Overview

Board mount AC DC converters are electronic devices that convert alternating current (AC) from mains power to direct current (DC) at required voltage levels. These components are critical in modern electronics, enabling power supply to printed circuit boards (PCBs) across diverse applications. They ensure safe voltage transformation, electrical isolation, and stable power delivery in compact form factors.

2. Main Types & Functionality

Type	Functional Characteristics	Application Examples
Isolated AC-DC Converters	Provide galvanic isolation between input and output circuits	Medical equipment, industrial controllers
Non-Isolated AC-DC Converters	Direct connection between input and output with shared ground	Consumer electronics, LED lighting
Modular AC-DC Converters	Standardized footprints with integrated EMI filtering	Telecom infrastructure, test equipment

3. Structure & Components

Typical construction includes: - Die-cast aluminum housing with heat dissipation fins - PCB assembly with bridge rectifier, PFC circuitry, and switching MOSFETs - Transformer for voltage conversion and isolation - Output capacitors and voltage regulation ICs - Safety-certified insulation barriers between primary/secondary sides

4. Key Technical Parameters

Parameter	Description & Importance
Input Voltage Range	90-264VAC (global compatibility)
Output Power	3-500W (determines load capacity)
Efficiency	85-94% (impacts thermal management)
Isolation Voltage	1500-3000VAC (safety compliance)
Operating Temperature	-40 C to +85 C (environmental reliability)
