Abstract
The present disclosure relates to a capacitive deionization system which makes use of a controller, a first capacitor acting as a first electrode, a second capacitor acting as a second electrode, and a first inductor for storing energy received from the first capacitor, and transferring the stored energy to the second capacitor. A first plurality of electronic switches are controlled by the controller to control communication between the first inductor and the first capacitor, and between the first inductor and the second capacitor. An additional energy transfer subsystem is included which has a second inductor for receiving energy from the first capacitor while the first inductor is transferring stored energy to the second capacitor.
