Diodes - Bridge Rectifiers W04G Application Field and Working PrincipleA bridge rectifier is an electrical device that produces an output voltage with a DC (direct current) component, as output from an AC (alternating current) input. In fact, bridge rectifiers are called this way because of their bridge-like configuration. They consist of several diodes arranged in a specific way to form what looks like a “bridge”. A bridge rectifier is used to rectify AC voltage to DC voltage and is a very common part of many electronic circuits. The most common type of bridge rectifier is the four-diode W04G bridge rectifier.The four-diode W04G bridge rectifier consists of four diodes connected in a bridge configuration. The bridge configuration is also sometimes referred to as “ladder bridge” or “ring bridge” configuration, as it resembles a ladder or a ring when set up correctly. The four diodes are connected in such a way that, when AC voltage is applied to the input, two of the diodes conduct at the same time, and the other two remain non-conductive. This connection arrangement allows current to flow in one direction only, and thus only one direction of the current is passed through the circuit.One major application of this type of bridge rectifier is in AC-DC power supply units. AC-DC power supply units are used to convert alternating current from the mains into a useable DC current that can then be used to supply power to various electrical devices. The W04G bridge rectifier is used to rectify the alternating current from the mains, so that all current flowing in the circuit is only able to move in one direction, resulting in a DC current that is suitable to power electrical devices.The W04G bridge rectifier also finds applications in various other electronic appliances and circuits, such as battery chargers, UPS units, solar panel charge controllers, Uninterruptible power supplies (UPS) and many others.The working principle of a W04G bridge rectifier is relatively simple. As already mentioned, four diodes are connected in a bridge configuration, with the anode (positive) side of each diode connected to one side of the AC voltage, and the cathode (negative) side of each diode connected to the other side of the AC voltage. The output of the bridge rectifier will be connected to the cathode side of the diodes. When the AC voltage is applied to the input of the bridge rectifier, two of the diodes will be forward-biased and two will be reverse-biased. This results in only one direction of the current being passed through the circuit, and the output voltage will be rectified DC voltage.In conclusion, the W04G bridge rectifier is a very common component used in many electronic circuits, particularly in AC-DC power supply units. It works by rectifying AC voltage to DC voltage, and is relatively simple in its design and working principle. As such, it is an indispensable component in many modern electrical devices and circuits.
