Figure 0.5, Full-Wave Bridge Rectifier Power Supply. A transformer is shown with no connections to its primary. It is presumed that the primary connects to the electric utility line in some way. The secondary connects to a bridge rectifier. A bridge rectifier is constructed as follows. The cathode of D1 connects to the anode of D2. The cathode of D2 connects to the cathode of d4. The anode of D4 connects to the cathode of D3. The anode of D3 connects to the anode of D1. One side of the transformer secondary connects to the cathode of D1 and the anode of D2. The other side of the secondary connects to the cathode of D3 and the anode of D4. The anodes of D1 and D3 connect to the negative output terminal. The cathodes of D2 and D4 connect to the positive output terminal. The positive end of a capacitor connects to the positive output terminal. The negative end of the capacitor connects to the negative output terminal. This completes the verbal description.
