Answer all the questions
What is the minimum value of capacitor C1 required such that Vfiltered does not drop below 8 V? Use the design equation(but make sure you use the right “frequency” and the correct ripple voltage). Show your calculations. Display your circuit in circuit js.
Display Vsecondary (can use the voltage across the added 100 kΩ resistor) and Vfiltered in a “Combined Scope”. Display VDC in a separate scope: a) Turn on “Max Scale”, “Show Peak Value” and “Show Negative Peak Value”: b) Run the simulator and adjust the window and simulation speed and time step to be able to see a couple of cycles. Include a screen capture
Document the minimum and maximum values for Vfiltered in your lab report. Is Vfiltered maintained to be above 8 V? By how much? Why? Explain the waveform shape captured Vfiltered. It may help your understanding to rerun the simulation with C1 removed and compare that waveform for Vfiltered to that captured

Internal combustion engines require a cooling system to function properly, which maintains the engine temperature at an appropriate value. Neither too high nor too low. There are several systems to control this temperature, the two best known are: • The classic one that uses a thermostat that regulates the flow of coolant (water), and where the fan is mechanically coupled to the engine. • In more recent vehicles, in addition to the thermostat, a temperature controller is used that turns an electric fan on and off.
