Abstract
A bi-directional switch for a power converter comprises first and second transistors (SW1, SW2) and a floating supply capacitor (C2) associated with the second transistor (SW2). The drive circuit and/or gate of the first transistor (SW1) is charged by the floating supply capacitor (C2) of the second transistor (SW2). The charging takes place at a predetermined moment in the switching cycle, and in particular at a moment in the switching cycle when the voltage across the bi-directional switch is substantially a minimum.
