Title: Capacitive deionization charge transfer from one capacitor simultaneously to multiple capacitors

Patent ·
OSTI ID:1576243

An energy transfer system is disclosed which has a controller, a first capacitor acting as a first electrode, a second capacitor acting as a second electrode, a first inductor for storing energy received from the first capacitor, and transferring the stored energy to the second capacitor, and a first plurality of electronic switches. The first plurality of electronic switches may be controlled by the controller to control a transfer of energy from the first capacitor to the first inductor, and from the first inductor to the first capacitor. An additional energy transfer subsystem may be included which has a second inductor for receiving energy from the first capacitor while the first inductor is transferring the stored energy to the second capacitor.
