Q1:Deyemine the values of all unspecified components in the power supply circuit.
Q2:Sketch waveforums at points A,B,C,D,E with correct timing relationship.
Suggested design procedure:
a) Understand the functions of rectifier,filter and voltage regulator.
b)According to the Zener voltage(9v,5.1V),select the appropriate Zenter diode form Table 1 with correspondent to the values of 1 zk,1zr and pD(max).
c)Calculate the values of 1zm(useing the values of PD(max) and Vz).
d)Claculate the ranges of R2 and R3 to ensure Zener diodes are in the Zener Breakdown Region.(Hint:Equation 4 of pg4 1)
e)Determine the resistances of r2 and R3 at its test current 1ZT,and verify the Zener diodes are poerating within their specidied current range.(Hint:Calculate 1z using max load current given)
f)Based on the specification given,from table 2.4(a)of your textbook,selsct a diode type by considering the values of 1o,1FSM and VRRM required to do the job (find PIV of each diode).
PD(max)=1W for all types
Type No.Nominal Zener Test current Knee Current

我是学生,不知道哪个答案才是正确的.请高手指教.

Q1 ：Deyemine所有非特指的组分的价值在电源电路的.
Q2 ：在点A,B,C,D,与正确时间关系的E的剪影waveforums.
Suggested设计程序：
a)了解整流器、过滤器和电压调整器的作用.
b)根据Zener电压(9v,5.1V),选择与通讯员的适当的Zenter二极管形式表1对1 zk、1zr和pD的价值(最大).
c)计算1zm的价值(使用(最大) PD和Vz的价值).
d) Claculate保证齐纳二极管的R2和R3的范围在Zener击穿范围.(提示：pg4 1)的式4
e)确定r2和R3抵抗在它的测试当前1ZT,并且核实齐纳二极管在他们的specidied当前范围之内poerating.(提示：计算1z使用指定的最大载荷潮流)
f)基于从表给的,规格2.4 (a要求的)您的课本、selsct二极管类型通过考虑1o的价值,1FSM和VRRM做工作(发现每个二极管PIV).
