Q4. Most electronic systems need a dc voltage to work properly. The AC-to-DC power supply system is including a transformer, a rectifier and a capacitor input filter. The AC input voltage is 110 Vrms at 60 Hz. (a) Draw the full wave bridge rectifier circuit with transformer which steps down voltage to safer and lower levels that are more suitable for use with diodes (b) Show how the capacitor input filter connects to the rectifier output in the...

1. Power supply (ac to dc) design. [10 pts.] Design a full-wave bridge rectifier circuit to deliver 10 volts dc with less than 0.1 volt (peak to peak) ripple into a load drawing up to 10 mA. (a) Choose the appropriate ac input voltage from the transformer secondary assuming the usual voltage drops for silicon diodes. (b) Determine the correct capacitor value to ensure the specified ripple in your calculation (c) What fuse value should you select for the primary...

It is required to use a FULL-wave rectifier to design a dc power supply that provides an average dc output voltage of 15 V. A maximum ripple voltage of ±1 V is allowed on the output voltage. The output voltage will feed a load resistance of 250 Ω. Assume a sinusoidal input voltage with the frequency of 60 Hz. Do not include a Zener diode in your design. (Assume V_D0)* = 0.7 V). a) Draw the circuit diagram. b) Calculate...

1. Is the power supply for a transformer AC or DC? Explain in detail why only this type of power supply will work. 2. Some configurations with the iron core have low efficiency while others have high efficiency. What is the iron core doing to cause this? Be specific. (Hint: think about how a transformer works.) 3. For an ideal transformer the energy must be conserved, so the average power (P=IV) in the two circuits must be equal. Therefore, if...
