Working Principle of MBR20H100CT/45

The MBR20H100CT/45 is a full-controlled bridge rectifier device composed of four metal-oxide semiconductor field effect transistors (MOSFET) and one Schottky diode rectifier. This device utilizes an active clamping resistor, which causes the voltage applied to the Schottky-diode rectifier to operate at a low voltage drop across it. This helps to reduce switching losses in the device.

When an AC voltage is applied to the device, the MOSFETs switch on and off with a controlled frequency. As the voltage waveform goes through its peaks and troughs, the MOSFETs respond to the changing voltage by switching on and off to allow the current to flow from one of their ends to the other. In this way, the device functions as a rectifier bridge, allowing the current to pass through in one direction only.

At the same time, the Schottky-diode rectifier is actively clamped by a resistor, reducing the voltage drop across it. This helps to reduce switching losses and improve the efficiency of the device. The active clamping is also responsible for providing a low voltage drop across the MOSFETs, which makes them operate at higher speeds. This improves the speed of the device and increases its performance.
