Component Specifications

Definition
A rectifier circuit is an electronic component within a High-Efficiency LED Driver Module that converts alternating current (AC) input into direct current (DC) output, essential for powering LED lighting systems with consistent voltage and minimal ripple. It typically includes diodes arranged in configurations like bridge rectifiers to ensure efficient energy conversion and compatibility with various AC sources.
Working Principle
Operates by using semiconductor diodes to allow current flow in only one direction, rectifying AC input into pulsating DC, which is then smoothed by capacitors to produce a stable DC output suitable for LED operation.
Materials
Semiconductor materials (e.g., silicon diodes), copper conductors, insulating substrates (e.g., FR-4 PCB), and protective coatings (e.g., epoxy resin).
Technical Parameters
  • Efficiency >90%
  • Input Voltage 85-265V AC
  • Ripple Factor <5%
  • Output Voltage 12-48V DC
  • Operating Temperature -40°C to 85°C
Standards
IEC 61000-3-2, UL 8750, EN 61347-1
