B484G-2 Application Field and Working Principle

The B484G-2 is a rectifier-array module specifically designed for DC/DC converters, motor control applications and other power conversion applications. This module is composed of two high-efficiency diode arrays with reversed polarity and two MOSFETs suitable for a wide range of input and output voltages. It is capable of switching a range of high voltages, up to 1.5A continuous and up to 10A peak.

The field of application of the B484G-2 is primarily focused on DC/DC conversion and motor control. The module’s two circuits can be utilized to protect power supplies from input over or under voltages as well as providing sustained current output. This is done by providing a regulated voltage within a specific range in order to stabilize power inputs and outputs. The two circuits can also be combined to provide more advanced circuit protection for DC/DC converters.

Working Principle

The B484G-2 module features two diodes and two MOSFETs. The diodes, in combination with MOSFETs, ensure the device operates in a reverse-polarity fashion, preventing the recurrence of an overload. The output of the device is connected to the load via the MOSFETs. The device is connected to a voltage source, either AC or DC, and it is made up of two MOSFETs connected in series. The current flowing through the load is determined by the voltage of the source, hence enabling the control of current. The two MOSFETs work together to form a bridge configuration that enables effective power switching.

The MOSFETs also provide switching protection. This prevents the B484G-2 module from being subject to over voltage or over current conditions. This feature is particularly useful in motor control applications, as it allows the B484G-2 to protect motors from damage due to excessive current and voltage variations. The MOSFETs also provide a the control voltage for controlling the current output, making it possible to select the optimum output for the application.

The B484G-2 modulealso includes protection for output undervoltage. This feature prevents the over-discharge of the power source and allows for a longer service life. Additionally, the module features a low-voltage shutdown mode to indicate when there is a low-voltage situation. This mode can be used to trigger a suitable action, such as shutting down the power source.

Conclusion

In conclusion, the B484G-2 is a rectifier-array module designed for DC/DC conversion, motor control applications and other power conversion applications. It is capable of switching a range of high voltages, up to 1.5A continuous and up to 10A peak. The module is protected from overvoltage, overcurrent and low-voltage conditions, allowing it to provide sustained current and voltage outputs. The B484G-2 is a reliable and efficient solution for power applications.
