Record down the following ratings at 25 degrees Celsius. Max Power Rating, Pmax; Typical Zener Voltage, Vzo: Typical Zener Impedance Zz: Zener Knee Current, Iz, knee:_ Maximum allowable Zener current, Iz,max= Although I had specified an R5 value of 1KQ; this is by no means the optimal Value to Use. You must design and choose your own value for R5. Since your Zener Regulator circuit will be coupled with your Capacitor-Filtered Rectifier Circuit, Use a V2 Value such that Vimin < V2< Vfmax, as your DC Voltage source in this independent Zener Regulator design. Design R5 such that, (1) The Zener with never exceed Iz, max calculated above and (2) even for no load (Open circuit Load); the current through the Zener will be below Iz,max but at the same time your Specification for the Line Regulation could be met. Show your design calculation below. R5 min = Value of R5 Such that your Line Regulation Specification will be Met = Practical Choice of R5=_ Next Calculate the No-load Current value of the Zener and Verify that it is below the maximum allowable Zener Current. Show your calculations below: Miami Dade College Spring 2024---EET 1141C IZNL:_ Using this Current, Calculate the No Load Voltage VNL: Next calculate the minimum load resistance Exam 1 To Be Concluded in 3 Hours RL,MIN: Practical Choice of RL,MIN=_ Replace the Load Resistor with two Resistors in series. (1) Your Choice of RL,MIN and (2) a 100KQ Potentiometer. This will ensure that while turning the potentiometer, your Total Load Resistance Varies from a minimum of RL,MIN to a maximum 100K+ RL,MIN. 4 Miami Dade College Spring 2024---EET 1141C Step 5: Simulating the Zener Voltage Regulator Setup the circuit in Multisim or PSPICE and Simulate the Circuit while Keeping the Load Resistance Constan at RL,MIN but Varying the Voltage source V2 from.
