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

TypeFunctional CharacteristicsApplication Examples
Isolated AC-DC ConvertersProvide galvanic isolation between input and output circuitsMedical equipment, industrial controllers
Non-Isolated AC-DC ConvertersDirect connection between input and output with shared groundConsumer electronics, LED lighting
Modular AC-DC ConvertersStandardized footprints with integrated EMI filteringTelecom 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
