POWER-CONVERTING APPARATUS FOR HYBRID VEHICLES

摘要

The present invention relates to a power-converting apparatus for hybrid vehicles, wherein inrush current, which might be generated in the event a DC link capacitor and an ultracapacitor are directly connected to each other and one of the capacitors is completely discharged or voltages charged in each of the capacitors are different from each other, is prevented by enabling voltages of the capacitors to correspond with each other via switching between the DC link capacitor and the ultracapacitor during the initial starting of an engine so that a load motor can be driven after the completion of the initial charge. Thus, the apparatus of the present invention can be safely initialized regardless of the charging/discharging state of an electricity storage device during the initial starting of an engine.
