I've searched the forums but have not found what I'm looking for. The problem at hand is that I have no idea how to successfully calculate the ripple over the load in this schematic:
I know that Vripple = i / 2fC where i is the current over the load. But this is the ripple over/in R1. Not over the load. So the question is, how do I calculate the voltage ripple on Rload? I thought some kind of voltage divider. When I attempt it I compare the values to the simulated values I get in Multisim. Not even close which makes me think that I have absolutely no clue where to start.
Some values that might be useful: Vpeak = 16.97 V, Voltage drop of 0.7 over each diode, zener voltage is 10 V. Everything else is given in the circuit above. Zener current in this circuit is (15.57-10)/180 = 31 mA
Thanks for any advice and pointers.
EDIT: Is this it? I still have no idea how to calculate ripple though. The voltage over the capacitor will not change so it will always be 15.57 volts. More tips? I honestly have no idea what to do next. In my head everything in this value in this circuit changes based on the load which makes this so much harder to calculate.
