Abstract:
A method of balancing voltage distribution over a plurality of switches connected in series with each other in a high voltage (HV) switch is provided. A snubber arrangement is associated with each switch of the plurality of switches. The method includes, for a first snubber arrangement associated with a first switch of the plurality of switches, determining a first voltage across a first snubber energy storage component of the first snubber arrangement associated with the first switch. The method further includes, for a second snubber arrangement associated with a second switch of the plurality of switches, determining a second voltage across a second snubber energy storage component of the second snubber arrangement associated with the second switch. The method further includes comparing the first voltage and the second voltage and, based on the comparison, adjusting a first drive signal of at least the first switch based on the first voltage.
