MBR10H100CTHE3/81 Diodes-Rectifiers-Arrays Application Field and Working Principle

The MBR10H100CTHE3/81 is a high power π-mode array 3-phase bridge rectifier. It is a type of a single-phase rectifier diode-array device used in a bridge rectifier circuit. A bridge rectifier composed of four diodes is a simple linear rectifier circuit that converts AC voltage to DC voltage. The bridge rectifier circuit is since it is the most efficient and reliable way to make a rectifier.

Its application field includes output filtering of switching power supplies, motor-driven systems, UPS power supplies, and battery chargers. The maximum repetitive reverse voltage of the device is 600 V and its maximum forward peak pulse current is 100A. It comes in an SMB package.

Working Principle

The working principle of the bridge rectifier is based on the action of the diodes. Diodes are basically electrical components that allow current to flow in only one direction. The diodes are arranged in a bridge configuration, which makes it possible to convert alternating current (AC) to direct current (DC).

When the bridge rectifier receives an AC voltage from the transformer, it is “rectified”. This means that the AC voltage is converted to DC voltage. The AC voltage is rectified when the diodes conduct only in one direction. When the voltage cycles, the diodes “open” and then “close” again, allowing the flow of current in another direction.

The output of the rectifier depends on the voltage received and the amount of current that the diodes need to sustain the bridge circuit. The bridge rectifier will supply a pulsed DC voltage, which is the output of the rectifier circuit. This pulsed current then needs to pass through a filter to become a filtered DC voltage. The filtered DC voltage is the output of the bridge rectifier circuit.
