Diodes - Rectifiers - Arrays comprise a broad range of products that in some way convert AC to DC current. The VB40M120CHM3/I Rectifier Array falls into this category. This components’ purpose and operation are discussed below.

Application Field

The VB40M120CHM3/I Rectifier Array is designed for high-efficiency and high-output power supply applications. It is widely used in notebooks, all-in-one PCs, TVs, display monitors, electronic gaming systems, portable electronic devices, set top boxes, home appliances, and various industrial automation systems. This component is well suited for applications for which a low power consumption and a high EMI attenuation is needed.

Working principle

The VB40M120CHM3/I Rectifier Array relies on a MOSFET, which operates according to a Field Effect Transistor (FET) principle to convert AC to DC current. In FETs, the gate voltage allows a voltage potential to be developed between the source and the drain. This is the voltage potential that is applied to the MOSFET. When the capacitor is charged, the field effect of the FET creates a current path between the drain and the source. This creates a flow of current through the MOSFET and creates a voltage drop across the MOSFET. This voltage drop is the output of the FET and provides a constant current output.

The VB40M120CHM3/I Rectifier Array also uses a relay to switch the MOSFET on and off. The relay is controlled by the processor that is programmed with the user’s settings. When the settings are changed, the processor will control the relay to switch on and off the MOSFET, resulting in different current outputs for different settings.

The VB40M120CHM3/I Rectifier Array uses two parallel circuits to achieve a higher efficiency and to reduce the power consumption of the device. The parallel circuits include two diodes, one MOSFET and one relay. The diode prevents current from flowing in the reverse direction and the MOSFET allows current to flow in the forward direction. The relay switches the power supply on and off. This parallel circuit allows the rectifier array to achieve high efficiency while consuming less power compared to conventional rectifier designs.

The VB40M120CHM3/I Rectifier Array is also designed to reduce EMI (electromagnetic interference) levels, because it uses a constant frequency for operation. This eliminates the high-frequency components associated with other circuits. It also reduces the amount of electromagnetic radiation that is emitted from the peripheral components.

In addition, the VB40M120CHM3/I Rectifier Array also has in-built safety features such as thermal protection and current limit protection. Thermal protection limits the temperature of the device to ensure it does not exceed the safe operation level. Current limit protection helps to prevent overloading by automatically shutting down the device if the current exceeds a certain level. This helps to protect the device and other connected components.

Conclusion

The VB40M120CHM3/I Rectifier Array is a highly efficient and low power consuming component that is used to convert AC to DC current. It is widely used in a range of applications, such as notebooks, TVs, display monitors, set top boxes and home appliances. It is also designed to reduce EMI emissions and includes safety features such as thermal protection and current limit protection.
