<p>The system has a control unit (121) for controlling switching of first and second switching cells (112, 120) according to a corresponding control law, where the control law is implemented such that current flows through a capacitor (116) at a given value of alternating output voltage in a direction during a first phase and in another direction during a second phase. The first cells are connected between each other by an intermediate point (114). The first cells are connected between an output terminal (108) and a mid-point (118).</p> |
