How Does a Bridge Rectifier Work?
Diode Bridge Rectifier Basics A diode bridge rectifier is a device for converting AC, or alternating current electricity into DC, or direct current. AC electricity goes from positive to negative constantly, whereas DC always flows in the same direction. AC electricity is more efficient to transmit and easier to convert into different voltages, so power is transmitted from the station to your house as AC. However, most appliances need DC current to run. A diode bridge rectifier is the most common type of power supply used to provide this current. The Transformer First, a transformer is used to create the desired voltage. When two coils are placed next to each other and a moving electric current is run through one coil, it induces a moving electric current in the other one. When the second coil has fewer turns of wire than the first coil, it will have a lower voltage current. This is called a step down transformer. Electricity comes into the house at 120 volts, but most devices need abou
