MURF20020

The MURF20020 is a popular diodes rectifier array product that is used primarily in alternating current (AC) applications. It is a three-terminal diode device composed of two distinct structures: one diodes bridge and a second filter rectifier. This device is commonly used in applications such as inverters, UPS systems, HID lighting and DC controllers. The MURF20020 is configured according to the particular application requirements, with the two structures having different functions.

Application Field: The MURF20020 has wide application in AC applications. Its three-terminal structure allows for flexibility in applications. In inverter applications, for instance, the diode bridge rectifies the alternating current allowing for electronic tuning of the output voltage. In UPS systems, it is used to provide surge protection in order to protect against the power outages. In HID lighting, it serves to regulate the current by converting the AC to DC. Lastly, it can also be employed in DC controllers in order to regulate the current.

Working Principle: The MURF20020 utilizes a diode bridge and a filter rectifier in its three-terminal structure. The diode bridge is responsible for converting alternating current (AC) to direct current (DC). It is composed of four diodes arranged in a bridge circuit configuration. At the same time, the filter rectifier provides additional protection and filtering action. This structure combines the current rectifying capabilities of the diode bridge with the filtering capability of the filter rectifier, resulting in a more efficient output.

Once the AC current is rectified, the device is capable of creating a DC current from the AC signal. This is accomplished by controlling the current through the diode bridge. By controlling the current, the bridge can provide a more efficient output than a traditional diode bridge by allowing for more efficient regulation of the current. The application-specific current limit of the MURF20020 can be adjusted by changing the operating voltage, making it possible to adjust the current based on the application requirements.

Once the current has been rectified, the current passes through the filter rectifier. The filter rectifier serves to provide additional filtration of the current by helping to reduce the harmonic distortion that is common in AC applications. The filter rectifier is also responsible for providing protection against short circuits and ensuring that the current is within the required limits.

The MURF20020 is a three-terminal device that provides effective AC rectification. Its two components, the diode bridge and the filter rectifier, combine to create a device that is capable of providing the highest levels of current rectification and filtering action. It is well suited for use in various applications and can be configured according to the particular needs of the application.
