Abstract

A hybrid power source consisting of electric double layer capacitor (EDLC) and battery is proposed. The load allocation in this power source is determined so as to reduce the repetitive charge and discharge operation of battery. This operation contributes the life extension of battery. In addition, a buck-boost converter which prevents DC-link voltage from charging by the decrease of EDLC voltage is introduced in this power source. Experimental results illustrate that the proposed hybrid power source reduces the utilization ratio of battery without varying DC-link voltage of voltage source of inverter.
