Power Supply Rectifier Board

Description:

A Power Supply Rectifier Board is an electronic module that converts AC (Alternating Current) to DC (Direct Current). It typically includes a bridge rectifier (diode bridge) to rectify AC, filter capacitors to smooth the DC output, and sometimes voltage regulators to provide a stable output voltage. These boards are used in power supply circuits for various electronic applications.

Specifications:

The specifications of a rectifier board vary depending on the design, but common features include:

• Input Voltage: 110V-220V AC or lower AC voltage (e.g., 12V, 24V AC)
• Rectifier Type: Full-wave bridge rectifier (using diodes like 1N4007 or Schottky diodes)
• Output Voltage: Typically 5V, 12V, 24V DC (depends on design and regulator used)
• Current Rating: 1A – 10A (or higher for high-power applications)
• Filter Capacitors: Large electrolytic capacitors (e.g., 1000µF, 4700µF) to smooth output
• Voltage Regulators: LM7805 (5V), LM7812 (12V), LM317 (adjustable output)
• Protection Features: Overvoltage, overcurrent, and short-circuit protection (in some designs)
• Board Size: Varies by design (e.g., 50mm × 30mm for small modules)

Applications:

Power supply rectifier boards are widely used in various electronic and industrial applications, including:

1. Embedded Systems: Provides stable DC power for microcontrollers and sensors.
2. LED Drivers: Converts AC to DC for powering LED strips and lights.
3. Battery Chargers: Used in charging circuits for lead-acid, lithium, and NiMH batteries.
4. Industrial Power Supplies: Powers control systems and automation equipment.
5. Audio Amplifiers: Converts AC to DC for powering amplifier circuits.
6. Household Electronics: Used in adapters and SMPS circuits for TVs, computers, routers, etc.
7. DIY Projects: Provides a simple power solution for hobby electronics and prototyping.
