Abstract: An industrially applied LCC power converter
is modelled as a hybrid system. It is found that the hybrid
system with three continuous states and one logic state
given a parameter set up and different initial conditions
has among other solutions one central closed trajectory
and two types of limit cycles, on the left and the right side.
The other solutions are indicated.
Summary in Swedish: En industriellt tillämpad LCC omvandlare är modellerad som ett hybridsystem. Det hybrida systemet modelleras med tre kontinuerliga tillstånd och ett logiskt tillstånd. Givet den industriella parameteruppsättningen och olika differentialvärden har systemet lösningar som bland annat en sluten bana och två gränscykler. Andra lösningar är inikerade.
