Im new to circuits, so bear with me lol.
My homework assignment is to design a Full Wave Bridge Rectifier (Attached the circuit I built in pspice and the full description of the assignment below.) The rectifier is to have a filter Capacitor across the Load.
Given:
Input = 120vrms, 60Hz
Load = 155 Ohms
Voltage Across individual diodes = .7V (1.4 together)
The Avg Outpt Voltage is to be 15v with a ripple of + 1V peak
I have to determine the Outpt Voltage, the peak to peak ripple voltage and the Avg/Max diode currents.
120Vrms = 170v pk (Vrms= Vpk/sqrt2)
with the voltage drop from the diodes (1.4v)
(1201.4)sqrt2=Vpk=168Vpk
The ripple frequency is double the source
60Hz> 120Hz
Vripple = Iload/fC
The problem im having is that I do not know the value of the capacitor to use nor the Load current, and im not sure how to incorporate the transformer. (was told to use 1Henry for the L1 Value not sure about L2)
