A choke input supply can be visualized as a capacitor input pi-filter, with the input capacitor removed. Hmmm....Better patent this mode switch before the greedy patent collectors of trivial devices get to it.

Hmmm....Better patent *this* mode switch before the greedy patent collectors of trivial devices get to it.
