Abstract
A voltage source converter is configured to generate a pulse train using two voltage levels. The voltage source converter includes a first converter arm coupled between a junction and a first DC terminal having a first voltage level and a second converter arm coupled between the junction and a second DC terminal having a second voltage level. At least one of the first and second converter arms comprises cells. A string of capacitors is coupled between the first and second DC terminals. A control unit is configured to control a group of cells used in a transition between the first and second voltage levels for commutating a current running through a corresponding one of the first and second converter arms involved in the transition.
