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 ...

Derivation of ripple factor equation for a full-wave rectifier with filter
I'm trying to derive the ripple factor for a full wave rectifier with a filter.
This parameter is defined as the ratio of the root mean square (rms) value of the ripple voltage (Vr_rms) to 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 ...

Output voltage ripple considerations
I'm working on a full bridge DC-DV converter, following the instructions on power supply cookbook.
It has a 350 V output, 2 kW total power, and a 30 kHz switching frequency. I chose a 5% inductor ...
