ABSTRACT:
A power storage device such as a capacitor, a battery or the like having a power storage element and a case, and a power converter using the power storage device in combination with an invertor circuit. The power storage device including a capacitor, a battery or the like is constructed of a power storage element having an anode foil, a cathode foil and an insulating material, and a highly thermally conductive and electrically conductive case, where an electrode foil of the power storage element is thermally insulated from the case by an insulating material and is in thermal contact with the case. The power storage device and the invertor circuit are arranged in close proximity and in thermal contact with a cooling unit. With this configuration, it is possible to prevent a leak current from flowing into the case to eliminate the generation of noise, maintain the security, and accomplish a longer effective life, a reduced size and a higher capacitance.
