Abstract
A converter power unit comprises: a heat sink; n power switch modules on the heat sink; a first group of laminated bus bars comprising a first and a second bus bar; a capacitor group comprising m capacitor; a second group of laminated bus bars comprising a third and a fourth bus bar, the first bus bar is connected with the third bus bar, the second bus bar is connected with the fourth bus bar; providing that vertical projection areas projected by an area occupied by the n power switch modules and projected by the capacitor group on a first plane perpendicular to an axial direction of the capacitor group are defined as a first and a second projection areas respectively, the first and the second projection area have an overlapped area. The present application can reduce the stray inductances in the commutating loop of the converter.
