Diodes - Bridge Rectifiers Application Field and Working Principle

Bridge rectifiers are essential components of power supplies, both low and high power. Their main purpose is to convert the AC voltage or current available from the power line into DC. They are commonly used in electronic circuits such as power inverters, uninterruptible power supplies (UPSs), voltage regulators, AC/DC adapters, and charging circuits. The VS-90MT120KPBF bridge rectifier is a popular, high power, single-phase bridge rectifier. A bridge rectifier is composed of four diodes connected in a closed loop (bridge configuration), as shown in the figure below. By connecting the diodes like this, current is allowed to flow in only one direction – from the positive side of the AC source to the negative side. The current will not have any ambiguity between the positive and negative terminals, while the output will be always DC or rectified AC. The VS-90MT120KPBF is a popular bridge rectifier, used in AC/DC adapter applications. It features a low-leakage current of under 2A, a forward voltage drop of 2.5V, a power dissipation of 245W, and an operating temperature range of -40°C to +125°C.The working principle of a bridge rectifier is that, during the positive half cycles of the AC source, one of the upper diodes conducts, while one of the lower diodes provides the return path for the current. At the peak of the positive cycle, the voltage point of the diodes is slightly higher than the input voltage. During the negative half cycle, the upper diodes turn off and the lower diodes conduct in the same way as the upper diodes did during the positive half cycle. At the peak of the negative half cycle, the voltage point of the diodes is slightly lower than the input voltage.In summary, the VS-90MT120KPBF bridge rectifier is a high-power, single-phase device used in a wide range of power-supply applications. It has a low-leakage current and a wide operating temperature range, making it suitable for a variety of environments. Its working principle is that it converts AC voltage or current from the power line into DC.
