GBU4M-E3/45 bridge rectifiers are used mainly in applications that require a DC output source, such as data center servers, converters, and battery charging systems. Among its many advantages are a compact size, high efficiency, low operating voltage range, tight voltage regulation, and low cost. In addition, bridge rectifiers have many other advantages that can provide long term reliability and improved efficiency in the end product.A bridge rectifier is a circuit composed of four diodes forming a closed loop. It is the most popular and reliable rectifier configuration used in power circuits. The bridge rectifier works on the principle of rectification which is the process of converting alternating current (AC), which reverses its direction periodically, into direct current (DC), which maintains one direction only.When AC voltage is applied at the two AC lines (Inputs), each diode will conduct with a forward bias in the direction shown, resulting in a push-pull type of action. During the positive half cycle of the applied AC voltage, diodes D2 and D3 become forward-biased and therefore act as low-resistance paths for current flow. As a result, current flows from the supply lines, through the diodes D1 and D4, then to the load. To return, the current has to flow through D2 and D3, completing the loop. The same process occurs during the negative half-cycle, resulting in the net flow of DC current through the load.The major advantage of bridge rectifiers is its capability to provide full-wave rectification even with a single phase input. In addition, the bridge rectifier is noted for its simplicity – only four diodes are needed, eliminating the need for a center tap transformer. As stated before, the bridge rectifier has a high efficiency, low operating voltage range, tight voltage regulation, and low cost.The GBU4M-E3/45 bridge rectifier is a perfect solution for extensively used applications such as switching power supplies, batteries, and industrial control systems. Its compact size helps to minimize the physical space footprint. Its high efficiency lets the system run at a higher power efficiency, reducing the total cost of power and improving the device’s reliability. Its low operating voltage range allows the system to be operated at lower voltages, saving power and increasing the overall system stability.As an example of its application, the GBU4M-E3/45 bridge rectifier can be used in a switching power supply system. This system uses a bridge rectifier to rectify AC voltage from the mains to DC voltage to be used by the switching regulation circuit. The bridge rectifier will ensure a constant voltage level to the regulation circuit, eliminating line noise and other disturbances.The GBU4M-E3/45 bridge rectifiers are well suited for many industrial applications with their high efficiency and low cost. Its superior voltage regulation and tight controls help keep a constant voltage level over varying mains input, making it a great choice for any application that requires a reliable and cost-effective power supply.
