Diodes - Rectifiers - Arrays are parts used in electronic circuits in order to rectify the AC voltage, reducing it to the corresponding DC output. The MUR2X060A02 diode array falls in this category, as it is designed to protect against surge currents and acts as a bridge rectifier - a device used to convert an AC current into an unidirectional DC output.

Application Field

The MUR2X060A02 is a three-phase rectifier, best suited for usage in high power applications like power conditioners, renewable energy systems, uninterruptible power supplies (UPS) and solar power systems. It also works excellent in electric car systems, providing a more reliable direct current if on-board AC power systems fail.

Working Principle

The MUR2X060A02 employs a three-phase full-wave rectification system for which it is essential to understand the design of the device itself. The device consists of an Array of 6 diodes arranged in 3 rows and 6 columns. The first row is connected to the AC incoming current while the other two rows are connected to a three-phase transformer which contains two additional windings, both with different number of turns to generate the rectified DC current.

The six diodes are connected in a way to achieve a full-wave operation. It is possible to have either three-phase full-wave bridge operation or a single-phase full-wave bridge operation, depending on how the diodes are connected. When the input AC voltage is applied to the first row, current flows from the negative AC half-cycle phase to the positive half-cycle phase.

During the negative half of the cycle, current flows through the diodes D1, D2 and D4, the transformer winding “1” and the load resistance R, in order to charge the filter capacitor C. Likewise, during the positive half cycle, the current flows from the diodes D3, D5, and D6, transformer winding “2” and finally the load resistance R.

This operation repeats itself four times to generate the direct current output. It is possible to adjust the number of output cycles, depending on the needs of the system. Additionally, the device is designed to protect against surge currents and high temperatures, allowing the rectifier to remain cool and efficient in high-power operations.

Conclusion

The MUR2X060A02 is a useful tool for a variety of high power applications, especially those related to renewable energy sources. Its three-phase rectification system ensures a stable and continuous DC output and its protection against surge currents and high temperatures, makes it a safe and reliable option.
