2. Rectifiers Back Objective: Define the term Rectifier Illustrate some basic Rectifiers Half-wave Rectifiers Full-wave Rectifiers Bridge-Rectifiers

3. Rectifiers Back Rectifier circuits are one method of converting AC to DC. By using a few components (discussed above) one can convert a simple sine wave into a DC voltage (all voltage is either always positive or always negative) Rectifier Circuit Sine wave input DC output

4. Rectifiers Back Combining the Transformer and Rectifier circuits allow isolation and amplitude adjustment of AC input signals to DC output. Sine wave input DC output Rectifier CircuitTransformer

5. Rectifiers Back Combining the Transformer and Limiter circuits allow isolation and amplitude adjustment of AC input signals to rectified DC output. Sine wave input DC output Rectifier CircuitTransformer

6. Half-wave Rectifiers Back Transformer and Rectifier Combination

7. Half-wave Rectifiers Back Follow the Electron Flow through each Alternation. Note the Frequency (in) = Frequency (out) Yellow = Vout Red = Vin First Half Cycle Second Half Cycle

8. Half-wave Rectifiers Back Follow the Electron Flow through each Alternation. Note the Frequency (in) = Frequency (out) Yellow = Vout Red = Vin

9. Full-wave Rectifiers Back Follow the Electron Flow through each Alternation. Note 2xFrequency (in) = Frequency (out) Yellow = Vout Red1 = Isecondary Red2 = Isecondary

10. Full-wave (Bridge) Rectifiers Follow the Electron Flow through each Alternation. Note: 2xFreq(in) = Freq(out) Yellow = Vout Green = Vin Red = Vsecondary Back

11. Full-wave (Bridge) Rectifiers A closer look at the waveform illustrates that this is not a smooth, Consistant DC output. We can change this by adding a filter to the circuit. Back
