Diodes - Bridge Rectifiers OverviewBridge rectifiers are able to transform AC electrical current into DC electrical current with the assistance of a group of diodes. This makes them suitable for a variety of applications: from providing DC voltage for general industrial and consumer devices, to more specialized uses such as AC voltage rectification and wave form conversion. The GBU402HD2G bridge rectifier from GITS is a great example of a bridge rectifier with a high current capacity and a wide temperature operating range.Application Field The GBU402HD2G bridge rectifier is designed to withstand high temperatures, ranging from -55°C to +150°C, which makes it suitable for many industrial applications. It is a two-legged bridge diode package consisting of two 1A diodes and two 2A diodes, enabling it to convert the AC current into DC current with low forward voltage drops. This makes it ideal for use in applications where a large amount of electrical current is needed, such as in high power appliances, control systems, motor drives, lighting control, and other electrical systems.The GBU402HD2G’s wide temperature operation also makes it suitable for applications where temperature fluctuates, such as in scientific and medical equipment, telecommunications, automotive, and aerospace fields. The high current capacity makes it a great choice for unconventional applications as well, such as welding and energy generation and storage.Working PrincipleThe GBU402HD2G bridge rectifier works by converting AC current into DC current. When a voltage is applied to the AC side of the rectifier, the diodes act as switches that direct a positive current to one end and a negative current to the other, resulting in DC current on the direct current side.The rectifier works in two ways: one-way (or half-wave) and full-wave. In one-way rectification, the diode only allows current to flow in one direction, while in full-wave rectification, the diode allows current to flow in both directions. The GBU402HD2G’s two-legged design enables it to perform both types of rectification, allowing for better control and flexibility in applications.Conclusion The GBU402HD2G bridge rectifier from GITS is a great example of a high current capacity, wide temperature operating range bridge rectifier. Designed for industrial applications, it can also be used for a variety of other applications such as energy generation and storage, welding, motor drives, and control systems. The diodes of this bridge rectifier are responsible for converting AC current into DC current, allowing for one-way or full-wave rectification depending on the application’s needs. With its versatile design and high-power capabilities, it is a perfect choice for a wide range of applications.
