Design a full-wave bridge rectifier circuit to deliver 10V dc with less than 0.1V(pp) ripple into a load drawing up to 10mA. Choose the appropriate ac input voltage, assuming 0.6v diode voltage drops.
The ac must output 10V + 0.6V + 0.6V = 11.2V RMS
which is about 16V amplitude.
Vripple = Iload / (2*f*C)
Assuming f = 60hz, C = 0.83 mF
Am I missing something?
I tried simulating this circuit using LTspice, here is the circuit:
probing the red node, I get this:
Obviously something is wrong.
Thank you very much.
