For the flyback converter, the input capacitor supplies the input current when the diode rectifier is off. The voltage discharge on the input capacitor, due to the input average current, should be within the limits specified. Assuming 25% ripple present on input DC capacitor, the input capacitor can be calculated as follows: ...
I have a personal project to charge/discharge high-voltage capacitors of 0.1-0.3 μF up to 1.5 kV at various levels (i.e voltage control.) I would like to use a standard flyback transformer topology operating from a 3.3-5 V DC input source for the charging.

Two distinct modes of operation are possible for the Flyback switching converters, shown in Figure 13-1: Discontinuous Mode All energy stored in the inductor is transferred to an output capacitor and load circuit before another charging period occurs. This topology results in a smaller inductor size, but puts a larger

It would be possible to capture inductive flyback energy in a capacitor, but doing so will make the motor run less smoothly and is thus only desirable if the intention is to induce vibration in the motor shaft. Instead, it''s much better to allow flyback current to flow as freely as possible with minimal voltage drop, and use a fast enough PWM ...

Capacitors found in old appliances across the 120v/230v mains are good for this, they''re called X class capacitors.
