MURB-16CT 16A Switchmode Power Rectifiers replace onsemi MURB16-CTG

The rectifier of a switch mode power supply refers to the component in a switch mode power supply (SMPS) that converts input alternating current (AC) to direct current (DC), typically a diode bridge. In a complete SMPS circuit, the rectifier converts it into pulsed DC power, which is then regulated by high-frequency switching devices, converted to voltage through transformers or inductors, and finally rectified and filtered to obtain a stable output DC voltage

 

The working process of rectifier in switch mode power supply

 

*Input rectification:

Firstly, the input AC power is converted into pulsed DC power through a diode bridge (rectifier)

*Filtering:

Connect a capacitor at the output of the rectifier to smooth the DC voltage and reduce ripple. 

*High frequency switch:

The rectified and filtered DC voltage is sent to high-frequency switching devices (such as MOSFETs), which continuously turn on and off at high frequencies, forming high-frequency pulse signals.

*Voltage Conversion:

High frequency pulse signals undergo voltage up and down conversion through transformers or inductors.

*Secondary rectification and filtering:

The converted high-frequency pulse signal passes through a rectification and filtering circuit again to obtain a stable and usable DC voltage output.

* Feedback control:

The output voltage is monitored through a feedback circuit and then adjusted by a control circuit to ensure that the output voltage remains at the set value during load changes and input voltage fluctuations

 

The function of rectifier

*Converting AC to DC: This is the basic function of a rectifier, which converts AC power from the grid into DC power suitable for electronic devices.

*Provide high-frequency pulse DC signal in the early stage:

By rectification, provide energy for the subsequent high-frequency switching process

 

There are many advantages when making use of Switch Mode Power Rectifiers:

• The design is compact – use wall, modular and rack structures – because the package is smaller, theconfiguration will be neat and unobtrusive.
• Switch Mode Rectifiers will save businesses money – they are cheaper to run than conventional SCR Units.
• High switching frequency enables less ripple.
• Many businesses will select and enjoy a precisely–controlled high current DC output with <2% AC Vrms
• Higher efficiency provides for a faster control loop.
