How does one compute the ripple currents seen by an active PFC output capacitor?
Suppose one is designing a single-phase power-factor-corrected power supply, with a known average current load:
The ripple current seen by the output capacitor is critical. If that current is too ...

Full-wave bridge rectifier with capacitor filter and ripple voltage
According to various sources, the ripple voltage of a full-wave bridge rectifier is
$$ V_r = \frac{V_s}{2}fCR $$
where \$V_s\$ is the peak of the input voltage source, \$f\$ is the frequency, \$C\$ ...

How does one compute the ripple currents seen by a boost converter output capacitor?
Suppose one is designing a boost converter, with a known maximum current load, and a known inductance:
The ripple current seen by the output capacitor is critical. If that current is too high, the ...
