Bridge rectifier circuit with a step-up transformer
I have been experimenting with a full-wave bridge rectifier in LTspice.
I am trying to step up 120 V AC/60 Hz to 1 kV DC for a load of around 2 kΩ. The step-up transformer has a ratio of 25:9. The ...

How do you find the peak-to-peak ripple voltage of a full wave bridge rectifier?
The 32VRMS secondary of a transformer feeds a full wave rectifier and capacitor filter as shown in
the circuit.
The peak-to-peak ripple of the output voltage of this circuit needs to be less than 1V ...
