Bridge RectifiersA bridge rectifier is a type of rectifier circuit that is made up of four diodes connected in a bridge configuration. It is used to convert an alternating current (AC) input signal into a direct current (DC) output signal. The diodes in the bridge rectifier allow current to flow in only one direction, which ensures that the output signal is always a DC signal with a fixed polarity. Bridge rectifiers are commonly used in power supply circuits, where they are used to convert the AC power from a wall outlet into the DC power that is required by most electronic devices. They are also used in other applications where AC to DC conversion is needed, such as in charging circuits for batteries.
