Abstract
A system for converting energy at a first voltage to a second voltage, including at least one source of voltage, a discharge switch, a variable capacitor, and a collection mechanism, connected in parallel, a charge switch between the discharge switch and the source, a transfer switch between the variable capacitor and the collection mechanism, and a controller to execute a control such that: a) during a first operation, the charge switch is closed to charge the variable capacitor, while the discharge switch and the transfer switch remain open; b) during a subsequent operation, the discharge switch is closed for a short instant while the charge switch remains open, allowing at least partial discharge of the variable capacitor.
