Abstract
A switching circuit for a voltage source converter includes a string of series-connected switches and a string of capacitors. A first conductor interconnects a first end of the string of series-connected switches with a first end of the string of capacitors at a first switch and a second conductor interconnects a second end of the string of series-connected switches with a second end of the string of capacitors at a second switch. A first string of components is connected between the first end of the string of series-connected switches and the first end of the string of capacitors and includes a snubber component for the first switch. A second string of components is connected between the second end of the string of series-connected switches and the second end of the string of capacitors and includes a snubber component for the second switch.
