Diodes, also known as rectifiers, are components that allow electricity to flow in only one direction and are commonly used in power supplies, light dimmers and voltage stabilizers. Bridge rectifiers are rectifiers that contain four diodes in the form of a bridge. The GBL04D2G is an axial leaded rectifier bridge, rated at 1000 volts with a blocking voltage of 1400v DC, a continuous current rating of 4A and a peak surge current of 100A. This bridge is used in various applications ranging from AC-DC power supplies to electric welding machines.

The working principle of the GBL04D2G is based on the diode bridge rectifier circuit. This type of rectifier uses four diodes in a bridge configuration to rectify an alternating current (AC) to direct current (DC). When an AC voltage is applied to the bridge, two of the diodes will be in forward biased condition, allowing current to flow through them and the other two will be in the reverse bias condition, blocking the current from flowing. This will cause the output voltage to be the same type of voltage as the input plus a small voltage drop from the diodes.

A key application for the GBL04D2G is in AC/DC power supplies. AC/DC power supplies use rectifiers to convert the alternating current from a power outlet into direct current that can be used to power electronic devices. In this application, the AC input is applied to the bridge where it is rectified to DC. The bridge rectifier provides better efficiency, power factor and lower harmonic distortion than a single phase full-wave rectifier.

The GBL04D2G bridge is also frequently used as a voltage regulator. In this application, the bridge is used to provide a constant output voltage regardless of the input voltage fluctuations. This is achieved by using the bridge together with a transformer to convert the input AC voltage to a fixed DC voltage. The transformer also provides voltage isolation, which helps to protect the circuit from high voltage or short circuit conditions.

The GBL04D2G is also commonly found in welding machines and other electric equipment. In welding machines, the bridge rectifier helps to provide a high quality arc by reducing harmonic distortion. This is done by turning the AC welding current into a DC arc. In electric equipment, the bridge rectifier is used to convert AC current to DC, as well as to regulate the voltage provided to the circuit.

The GBL04D2G is a versatile bridge rectifier, which can be found in a variety of applications due to its high voltage rating, current rating and surge capacity. It is an essential component in electronics applications such as AC/DC power supplies, voltage regulators and electric welding machines, as it can rectify voltages, regulate voltages, and improve the performance of electric equipment.
