1 ECE 1750 Week 3 (part 1) Rectifiers 1

2 Rectifier Rectifiers convert ac into dc Some commercial rectifiers: (Used to charge batteries like those on the right)

3 Example of Assumed State Analysis V ac R L Consider the V ac > 0 case We make an intelligent t guess that t I is flowing out of the source node. If current is flowing, then the diode must be on We see that KVL (V ac =I R L ) is satisfied Thus, our assumed state is correct 3

4 Example of Assumed State Analysis 1V 11V 10V R L 11V We make an intelligent guess that I is flowing out of the 11V source If current is flowing, then the top diode must be on Current cannot flow backward through h the bottom diode, d so it must be off The bottom node of the load resistor is connected to the source reference, so there is a current path back to the 11V source KVL dictates that the load resistor has 11V across it The bottom diode is reverse biased, and thus confirmed to be off Thus our assumed state is correct 4

5 Assumed State Analysis V ac R L What are the states of the diodes on or off? Consider the V ac > 0 case We make an intelligent guess that I is flowing out of the source node. I cannot flow into diode #4, so diode #4 must be off. If current is flowing, then diode #1 must be on. I cannot flow into diode #3, so diode #3 must be off. I flows through R L. I comes to the junction of diodes # and #4. We have already determined that diode #4 is off. If current is flowing, then diode # must be on, and I continues to the V ac terminal. 5

6 Assumed State Analysis, cont. V ac > 0 1 R L A check of voltages confirms that diode #4 is indeed reverse biased as we have assumed A check of voltages confirms that diode #3 is indeed reverse biased as we have assumed We see that KVL (V ac = I R L ) is satisfied Thus, our assumed states are correct The same process can be repeated for V ac < 0, where it can be seen that diodes #3 and #4 are on, and diodes #1 and # are off 6

14 AC Current Waveform 1 T = f The ac current waveform has significant harmonic content.
