Convert Alternating Current into Direct Current with Bridge Rectifiers from Sears

Whether you're building a radio or repairing a flat screen television, a bridge rectifier is a key component of the power supply needed to convert the electrical current and provide the right amount of voltage for the intended appliance. When you don't need a half-wave rectifier or full-wave rectifier, you need a bridge rectifier, and Sears has the bridge rectifiers you need to supply the proper amount of power to electronic devices. Get the right electronic components to build or replace circuits in your home, car or electronics.

The voltage coming into a standard household outlet is a lot higher than the amount needed for electronic devices like computers or HDTVs, so it needs to be converted to a lower voltage. That's where bridge rectifiers come into play, using transformers to create the desired voltage. Transformers allow you to simply convert the 120 volts coming into the standard outlet to the 10 or 12 volts required for most household appliances. Transformers are important components of bridge rectifiers as they relate to voltage, but the diode bridge makes the conversion from AC to DC possible.

A half-wave rectifier requires one single diode, and a full-wave rectifier requires two diodes. A bridge rectifier, which is available at Sears, requires an arrangement of four diodes in order to produce a direct current that is half the total output of the transformer. This conversion of alternating current to direct current at a lower voltage is the main purpose of the bridge rectifier and a common reason why some household appliances break down. Replacing the bridge rectifier in an electronic device that has lost power can be a good place to start if you want to repair it.

When one component of a bridge rectifier stops working, it can cause a whole device to lose power. It doesn't matter if it's a leaky diode, a broken transformer or faulty inductors, you may need to replace the whole rectifier. But use caution when replacing the components of an electronic device. Repair professionals should refer to instruction manuals when repairing bridge rectifiers in order to avoid harmful electric shocks. Novice or amateur repairmen should seek the advice of a professional before attempting to replace a rectifier.

Many common household items require a direct electric current to operate, but most household outlets have an alternating electric current output. That's why bridge rectifiers play such an important role in the repair of faulty electric appliances. When the power supply breaks down, sometimes it can be replaced. Let Sears help you find bridge rectifiers and other important electronic components needed to fix flat screen televisions, treadmills, and many more consumer electronic devices.
