On the Snubber Influence to the Switching and Conduction Losses in a Converter Using Switched Capacitor
Zusammenfassung
The paper deals to design and to compute the snubber parameters influence on
the switching and conduction losses of the transistors (IGBT) used as bidirectional
switches in a converter with switched capacitor. The converter was modelled with
difference equations, and the transistors during turn-on and turn-off processes were
simulated by dynamically varying resistance models. The energy loss per switching,
commutation time, the variation of the transistor voltage etc. and the influence of
snubber parameters in each of these cases are shown in the context of a converter used
as a 50Hz reactive power controller unit.
