A diode commonly referred to as a rectifier is a two-lead, semiconductor device primarily used to convert alternating current (AC) to direct current (DC). The EGX31A-E3/C is a single-phase rectifier bridge made of four discrete rectifying components, which can be used with power supplies or in motor control applications. It consists of four high-rugged 900V metal-oxide field-effect transistors (MOSFETs).

Features and Benefits

The EGX31A-E3/C rectifier bridge has a breakdown voltage of 900V, low forward voltage drop and low leakage current. It also features a low on-resistance of 12.6mΩ and a high forward surge current of 3A. The device is also short-circuit and over-temperature protected. These features make it an ideal choice for power supplies and motor control applications.

Application Field

The EGX31A-E3/C rectifier bridge can be used in a wide variety of applications, including power supplies such as switch-mode power supplies (SMPS), AC-DC converters, electric scooters or vehicles, as well as motor drives such as electric motors or brushed DC motors. For electric scooters, for example, the EGX31A-E3/C rectifier bridge can be used with a diode rectifier or a three-phase rectifier for the power stage.

Working Principle

The EGX31A-E3/C rectifier bridge works by converting alternating current (AC) from a power source (e.g. wall outlet) into direct current (DC). It is composed of four rectifiers that each consist of a MOSFET connected in a bridge configuration. When AC power is applied to the bridge, one of the rectifiers will conduct and the other three will remain in an off-state. When the current direction in the bridge changes, the rectifiers will switch their conducting and off-state. Thus, the rectified current flows in either one of the rectifiers, alternating between positive and negative, in the direction that the load requires.

Conclusion

In conclusion, the EGX31A-E3/C rectifier bridge is an ideal choice for power supplies and motor control applications. It has a 900V breakdown voltage, low forward voltage drop, on-resistance of 12.6mΩ, high forward surge current of 3A and is also short-circuit and over-temperature protected. This rectifier bridge is used to convert AC power from a source into DC power, and it works by switching the conducting and off-state of its four rectifiers.
