| Abstract |
This paper describes how soft switching can be used in serial connection of
power components in order to reduce overcurrents due to parasitic capacitances to ground during turn on. In hard switching, this phenomenon become crucial when the number of
serial connected switches increases. Indeed, the parasitic current in the lowest potential devices increases losses and can even exceed their pulse current rating. Particular attention is given to the way resonant inductors can be placed in series with devices in order to reduce these overcurrents. This makes the achievement of an over 50kV switch easier for the use in high voltage static converter. |
