After charging the capacitor, let the capacitor discharge with high power in a short time? I want to use an ordinary 24V switching power supply to charge a capacitor, and charge the capacitor to a value between 10V and 20V, which is equivalent to using the capacitor as a power supply, and then, waiting for the capacitor I need to discharge At this time, let the capacitor discharge for 3ms, and the discharge current reaches about 20A. After the discharge is finished, continue to be fully charged and wait for the discharge to be discharged again. Do you know how to complete this? thank you all.

The capacity of this capacitor must be very large, otherwise it will not reach 20A current. The solid state relay can be controlled by a timer or a single-chip microcomputer to discharge.

To make this circuit, you can use a high-current thyristor, but also add a control circuit. When the capacitor is discharged, disconnect the charging circuit of the power supply to the capacitor.

If the power supply continues to charge the capacitor, a MOS tube must be used, and the SCR is not suitable.
