<p>The method involves connecting parasitic capacitors (30, 34) to a highside switch (24) and a lowside switch (26), respectively. A current for a capacitive load (38) is conducted alternatively by switching-on one of the two switches by the other switch. The current after switching-off the former switch is charged during a change-over process by supplying zero-voltage transition in the parasitic capacitors of the latter switch. A free-wheel phase is converted during the change-over process of the switches, and synchronous rectification is carried out for the free-wheel phase. Independent claims are also included for the following: (1) an arrangement for charging a capacitive load with a bi-directional switching output stage (2) a computer program comprising a program code to execute a method for charging the capacitive load with the bi-directional switching output stage (3) a computer product comprising the program code that is stored on a computer-readable data medium to execute a method for charging the capacitive load with the bi-directional switching output stage.</p> |
