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
Calculations
120Vrms = 170v pk (Vrms= Vpk/sqrt2)
with the voltage drop from the diodes (1.4v)
The transformer has a ratio of 170:17 and a inductance ratio of (1/10)^2
The ripple frequency is double the source
60Hz> 120Hz
Iload= 15V/155Ohms
Vripple = Iload/fC
The transient analysis does not seem right, can someone help me figure out the problem (wiring or maybe the wrong capacitor value).
I attached a screenshot below.
