Diode Bridge Rectifier Waveform. This rectifier is mainly used for providing full wave rectification in most of the applications. A transformer is used in order to step down the voltage to a desired level at the output a load is connected which consumes power fig bridge rectifier circuit and waveform rectified.
A center tap full wave rectifier needs only 2 diodes whereas a bridge rectifier needs 4 diodes. The bridge rectifier consisting of four diodes enables full wave rectification without the need for a centre tapped transformer. The bridge rectifier is an electronic component that is widely used to provide full wave rectification and it is possibly the most widely used circuit for this application.
A diode bridge is an arrangement of four diodes in a bridge circuit configuration that provides the same polarity of output for either polarity of input.
Bridge rectifier construction the construction diagram of a bridge rectifier is shown in the below figure. But silicon diodes being cheaper than a center tap transformer a bridge rectifier is much preferred solution in a dc power supply. During the positive half cycle of the supply diodes d1 and d2 conduct in series while diodes d3 and d4 are reverse biased and the current flows through the load as shown below. The bridge rectifier is an electronic component that is widely used to provide full wave rectification and it is possibly the most widely used circuit for this application.
