Diodes - Bridge Rectifiers

A bridge rectifier is a device that uses four diodes in a bridge arrangement to convert alternating current (AC) to direct current (DC). The CDBHM120L-G bridge rectifier is an electronic component specifically designed to bridge AC to DC. It is widely used in various AC to DC applications and is capable of handling up to 120A of current.

Overview

The CDBHM120L-G rectifier is a robust, high-power diode package designed to meet any AC/DC power needs efficiently. The diode bridges are formed in a 4-pin package, with each pin acting as an anode or cathode. The voltage ratings of the individual diodes are 50V and the current ratings are 120A. The total device is rated at 120A, at 380V AC, in either a continuous or single surge current and can handle up to 800V in peak inverter applications. In addition, the device has a low junction temperature due to its ultra-low thermal resistance.

Applications

The CDBHM120L-G rectifier is primarily used for the following applications:• Motor control and power supplies• Uninterrupted power supplies (UPS)• Solar inverters• Industrial machines• Household appliances• Battery chargers• Power conditioning circuits• DC to AC converters• AC to DC converters

Working Principle

The CDBHM120L-G uses four diodes arranged in a bridge configuration to convert AC to DC. The AC input is applied to the bridge rectifier via two terminals, usually labeled “A” for the Anode and “C” for the Cathode. The two remaining terminals are called “D” and “GND”. When the AC input is applied to the bridge rectifier, the diode located at the “A” terminal allows current to flow from the Anode to the Cathode. When the polarity of the AC is reversed, the diode located at the “C” terminal allows current to flow from the Anode to the Cathode.This process repeats in a continuous cycle, constantly inverting the polarity of the current output. The bridge rectifier then produces a steady DC output across terminals “D” and “GND”. The advantage of using a bridge rectifier over a single-diode rectifier is that it eliminates any power loss due to the voltage drop across the diode. Even under varying load conditions, a bridge rectifier can produce a stable DC output.

Conclusion

The CDBHM120L-G bridge rectifier is a reliable and efficient way to convert AC to DC. It is designed for a wide range of applications requiring up to 120A of current, and can handle voltages up to 800V in peak inverter applications. In addition, it can maintain a stable DC output even under varying load conditions, making it an ideal solution for power conversion needs.
