POWER-CONVERTING APPARATUS FOR HYBRID VEHICLES

The present invention prevents an inrush current generated when one side is completely discharged, or charged voltages are different from one another because a DC link capacitor and an ultra-capacitor are directly connected to each other, by driving a load motor after completing initial charging by making each voltage the same through the performing of switching between a DC link capacitor and an ultra-capacitor during initial ignition, so as to safely perform initializing regardless of the charged-discharged state of an electricity storage device during initial ignition.
