How to Apply a Bridge Wave Rectifier?
A bridge wave rectifier is a specific configuration of diodes used to convert AC current, which alternates polarity periodically, to DC current, which is unipolar. A bridge wave rectifier converts the full AC wave by effectively flipping one polarity of the current to the other, producing a wave that flows in one direction with very little loss of voltage. Reversing the negative wave of the AC current produces the full-positive wave seen in DC current.
1. Study the schematic for a bridge wave rectifier. Focus on the arrangement of the four diodes and the directions they face.
2. Determine where in your circuit you need to convert AC to DC. Draw a schematic describing the flow of AC current to DC current and the output device or circuit the DC flows to.
3. Wire four diodes together in a bridge configuration, as described in the rectifier's schematic, with two diodes facing cathode-to-cathode and two diodes facing anode-to-anode. Solder the connections in place.
4. Connect the output device or circuit as described in the schematic. This connection intercepts the current from between the cathode-to-cathode diode pair and passes it between the anode-to-anode diode pair.
5. Wire this circuit to an AC transformer as described in the schematic. Connect the negative end of the transformer to the input of the circuit and the positive end to the output.
