It utilizes the advantages of of G10 material - low forward voltage drop, space-efficient, long lifetime, etc. The SE20AFGHM3/6B also features with good di/dt resistance performance, short reverse recovery time and is suitable for low dv/dt applications. It can be used in different circuits, giving reliable railway and field operation.

Application Fields

The SE20AFGHM3/6B single phase rectifier is suitable for the power supply field and voltage rectification. It is used in a variety of rectifier and voltage regulator circuits, such as: heavily loaded switch-mode power supplies, power transmission lines and busbars, charging systems, inverters, fuel-cell systems and automotive applications.

Working Principle

The SE20AFGHM3/6B single-phase rectifier works with the principle of electron motion. It includes a controllable rectifier on the left side with a pair of terminals, and a controllable diode on the right side with a pair of terminals. The diode pair is the two ends of the single-phase rectifier. The diode pair provides a strong electric field to the single-phase rectifier. This electric field induces an electric current to flow through the rectifier. The direction of the current is determined by the applied voltage. If the voltage is in the forward direction, the electric current will flow from the anode of the first diode to the anode of the second diode. If the voltage is reversed, the electric current will be reversed and will flow from the cathode of the first diode to the cathode of the second diode. This process of electron motion is used to convert alternating current (AC) to direct current (DC). The current produced by the SE20AFGHM3/6B can be adjusted by controlling the electric field in either direction.

Conclusion

The SE20AFGHM3/6B single-phase rectifier is suitable for different circuits, it can handle up to20 Amps of current and provide reliable operation. It has a low forward voltage drop and fast switching time, making it ideal for low dv/dt applications. It is easy to install and use and has a long lifetime of operation.
