Claim Text:
1. A voltage converter comprising: a primary path configured to generate a pulse modulated voltage or current from an input direct current (DC) voltage; a transformer arrangement with m≧1 primary windings and n≧2 secondary windings inductively coupled together, the m primary windings being connected to the primary path; and a secondary path configured to output a pulsed direct current (DC) voltage or current, wherein the secondary path comprises n capacitors connected in series and n secondary controllable semiconductor switches, and wherein each of the n secondary windings is connected via at least one of the secondary controllable semiconductor switches to at least one of the capacitors; and n soft commutation networks, each connected in parallel to one of the n secondary controllable semiconductor switches, wherein each of the n soft commutation networks comprises:
