output capacitance needed is calculated as:

The voltage rating on the capacitor needs to account for the

operation of the device before it hits the overvoltage protection

threshold. This is typically 105% of nominal value, which is

483 V. With the ripple voltage factored in, 22

μF of

capacitance rated at 500 V would suffice for this application.
