Abstract: |
The invention relates to the three electric levels integrated middle, high voltage frequency changer. It belongs to the electric power electron technology domain. It at least includes one set of three splitting step-down transformer, one set of the twelve pulse commutating unit, one set of the commutating absorbing unit, the fast protecting unit of the semiconductor switch apparatus of the mother line power, one set of the three electric level reverse changing unit having the function of power semiconductor device equaling the voltage automatically and the one set of the integration filtering booster unit. The invention solves the problem of high voltage frequency changer lacking of the bus power semiconductor switch device quick protecting unit. |
