DC Choke

In typical DC chokes the AC ripple flux is normally small in comparison to the DC component. These days most DC supplies come from switched mode converters which operate at 50-250kHz.

Other Details

In typical DC chokes the AC ripple flux is normally small in comparison to the DC component. These days most DC supplies come from switched mode converters which operate at 50-250kHz, which means that any ripple on the DC is at the same frequency. This allows for much smaller filter component values than used for 50/60Hz mains supplies.
