Chapter 4: Diode Circuits

Question 1

Half Wave Rectifier

Answer 1

Single Diode, returns only the voltage wave shape above axis

Question 2

Ideal Half Wave

Answer 2

V_P(out) = V_P(in)

Question 3

Half Wave Rectifier:

V_AVG

Answer 3

V_DC

Question 4

Half Wave Rectifier:

V_DC

Answer 4

0.318*V_P

V_P / pi

Question 5

Half Wave Rectifier:

Frequency Out

Answer 5

f_out = f_in

Question 6

Half Wave Rectifier:

V_P

Answer 6

V_P = Voltage / 0.707

Voltage * sqrt(2)

Question 7

Half Wave Rectifier:

DC Load Voltage

Answer 7

V_DC = V_P / pi

Question 8

Half Wave Rectifier:
Second Aprproximation
V_P

Answer 8

V_P = (Voltage / 0.707) - 0.7

Voltage * sqrt(2) - 0.7

Question 9

Half Wave Rectifier:
Second Approximation
DC Load Voltage

Answer 9

V_DC = V_P / pi

Question 10

Turn Ratio Derivation

Answer 10

V_2 = V_1 / (N_1/ N_2)

Question 11

Full Wave Rectifier:

Answer 11

Flips voltages below 0 across the axis

Question 12

Full wave

V_DC

Answer 12

(2V_P) / pi

Question 13

Full wave

f_out

Answer 13

f_out = 2f_in

Question 14

Full wave
Second Approximation
Vp_in

Answer 14

Voltage / 2

Since it is center taped you will only see half the voltage on each side of the tap

Question 15

Full wave
Second Approximation
Vp_out

Answer 15

V_P(in) - 0.7

Question 16

Bridge Rectifier

V_DC

Answer 16

V_DC = 2V_P / pi

Question 17

Bridge Rectifier

f_out

Answer 17

f_out = 2f_in

Question 18

Bridge Rectifier
Second Approximation
V_P(out)

Answer 18

V_P(out) = V_P(in) - 1.4V

since voltage goes through two diodes
