Bridge Rectifiers: BU1506-M3/45 Application Field and Working Principle

Bridge Rectifiers are electronic parts most commonly used to rectify alternating current (AC) input voltage to a direct current (DC) output voltage. Rectifiers are mounted in all sorts of DC appliances and equipment, from power-socket adapters to computers. BU1506-M3/45 is a bridge rectifier, which is a key component on the printed circuit board (PCB). It can be artificially generated with four diodes wired in a bridge configuration or, more practicably and commonly, buy one of the many commercially available packages of four diodes that are already pre-packaged in the same configuration.

Application Field of BU1506-M3/45

BU1506-M3/45 is a standard high-performance isolated four-diode bridge rectifier made by Shanghai Qianhong Microelectronics Technology Co., Ltd. It is widely used in high-quality AC/DC power supplies and AC/DC adaptors. Its features include ultra-low forward voltage drop, zero reverse current, low thermal resistance, and very low power losses. Its devices launched on the market are RoHS compliant, 100% lead-free, and deliver reliable, stable performance.

Working Principle of BU1506-M3/45

The working principle of the BU1506-M3/45 rectifier is to convert AC power into DC power. BU1506-M3/45 contains four diodes and a bridge rectifier circuit that converts the AC input voltage to DC output voltage. When an AC voltage is applied to the bridge, one diode conducts current from the positive to the negative side of the bridge and the other from the negative to the positive side of the bridge. This process is called bi-directional conduction.When the voltage across both sides of the bridge is equal, no current passes through the bridge. The diodes also provide protection against reverse polarity applications. When the voltage is of the wrong polarity, a signal called a clamp, or reverse voltage bias, is generated.This signal clamps or shorts the bridge and prevents current from flowing through it. The diode rectification process generates DC output voltage that is smooth, ripple-free, and proportional to the AC input voltage.

Conclusion

The BU1506-M3/45 bridge rectifier is a reliable piece of technology that can be used in a variety of applications. It offers great performance that is both ultra-low in forward voltage drop and zero in reverse current, and its RoHS compliance ensures it is 100% lead-free and environmentally friendly. With its superior performance and important safety compliance, the BU1506-M3/45 is ideal for applications where reliable DC power supplies and AC/DC adaptors are needed.
