SF11-T Bridge Rectifier Application Fields
The SF11-T Bridge Rectifier is used primarily in consumer electronics applications such as telecommunication systems and automotive electronics. It is also used in industrial power supplies as well as in medical, time and measurement, lighting and consumer products. In addition, it is also used in general purpose switching applications such as AC/DC rectification, motor control and inductive load switching.
SF11-T Bridge Rectifier Working Principle
The SF11-T utilizes a four-terminal or bridge configuration to advantageously shape the rectified wave forms obtained from a single phase alternating current sine wave source. This bridge configuration isolates the neighboring AC phases and eliminates cross-currents in the device. The Bridge Rectifier\'s operation includes a two pole switch with two diodes that are connected to form a half-wave rectifier. The two diodes are alternately connected to the AC input voltage so that when the switch is closed one of the diodes is forward-biased and the other is reverse-biased. This allows current to flow through the forward-biased diode but not through the reverse-biased diode. The half-wave rectifications are repeated until the duration of the input voltage is complete.
The other part of the SF11-T Bridge Rectifier is the output stage, which is a full-wave rectifier. It takes the rectified output waves from the input stage and combines them using four diodes in a bridge arrangement. The output from the bridge rectifier is taken from the positive or negative output terminal and is filtered. This will provide a DC output. The performance of the SF11-T Bridge Rectifier is determined by the following parameters: Forward voltage drop, current rating, thermal resistance and reverse leakage current.
Conclusion
The SF11-T Bridge Rectifier is a type of single-phase silicon bridge rectifier that offers low forward voltage drop and high peak current capability. It is suitable for low and medium power applications and is mainly used in consumer electronics, industrial power supplies and automotive electronics. Due to its high current handling capability, it can easily handle inductive loads and switching applications. Its bridge configuration provides isolation between AC phases and its output stage is capable of providing a full-wave DC output.
