The MXG/Y series of rotary diode bridge rectifier modules are rectifier modules used for brushless generators, primarily for converting the AC output of a brushless generator into DC for use by loads. These modules use high-performance silicon-controlled rectifiers and fast recovery diodes to achieve high efficiency, low leakage current, low voltage drop, and high reliability, while also providing various protection features such as overcurrent, overvoltage, and overtemperature protection to ensure safe operation of the brushless generator.

The core component of a rotary diode bridge rectifier is the rotary diode, which is a special type of diode that can frequently switch between forward and reverse at high frequencies to achieve rectification and filtering of the output voltage of the brushless generator. The MXG/Y series modules contain multiple rotary diodes to meet the requirements of brushless generators with different power and voltage levels.

Therefore, the MXG/Y series of rotary diode bridge rectifier modules are an important component of brushless generators, enabling the rectification and filtering of the output voltage of the brushless generator, as well as providing various protection features to ensure safe and efficient operation of the generator.

3-pin vs 4-pin
The 3-pin version of the MXG(Y) module is generally used for single-phase bridge rectifier applications, where the output has only two polarities and is connected to the negative pole of the module via a shared center pin. The 4-pin version, on the other hand, is suitable for three-phase bridge rectifier applications, where the output has three polarities and is connected to three separate pins that are each connected to a phase of the power supply.

In addition, the 4-pin version typically has a transistor driving function, which enables control of the module’s internal silicon-controlled rectifiers for more precise output control and protection.

Explanation
– IGT ,VGT ,IH are all TA =25℃ test data,others are all TA =T jm test data.
– I2t=I2TSM ×tW /2:tW=Half sine wave current,when at 50Hz,I2t=0.005I2TSM (A2S)
– When at 60Hz,ITSM (8.3ms)=ITSM (10ms)×1.066,Tj=Tjm I2t(8.3ms)=I2t(10ms)×0.943,Tj =Tjm

Requirements and Suggestions for module installation:
A) The installation surface of the module shall be smooth without scratches, bumps and sundries;
B) When installing the module to the heat sink, gently remove the oxide layer on the surface of the heat sink with fine sandpaper, wipe the surface of the heat sink with anhydrous ethanol, and then evenly apply a thin layer of heat-conducting silica gel on the contact surface of the copper base plate and the heat sink to make the contact good and reduce the thermal resistance;
C) When fastening the module on the heat sink surface, use M5 or M6 flat batten and spring washer, and fasten the screw with (5+1)Nm force distance;
D) The wiring of the main electrode of the module shall be copper strip with smooth, flat and sufficient contact surface. The contact must be good. The tightening moment of force shall be: If M5 screws are used, the moment of force shall be (3) Nm; If M6 screws are used, the moment of force is (5+1)Nm. If M8 screws are used, the moment of force is (9+1) Nm.
