- The output voltage of the bridge rectifier is the voltage across C1. It's not measured in your simulation circuit at all. PSpice has a voltage differential marker for this purpose.
- Alternatively, you can change the circuit ground from transformer star point to output V-.
- Without a load, the output voltage is just the input peak voltage. No realistic test setup for a filter. You should add a a load resistor or current source according to the intended output current.
- For a reasonable filter effect with usual output currents, the filter capacitor should be in a 1000 to 10000 µF order of magnitude.
- With a meaningful measurement setup, you'll see a 300 Hz ripple frequency.
