Claim Text:
1. A power conversion device comprising: an inverter that receives power from a power supply system and drives a motor that is connected to a first ground; a cooler that cools down the inverter; a first core including a through hole that allows passage of a positive side conductor that connects the power supply system and the inverter and a negative side conductor that connects the inverter to a second ground; a first ground conductor that is connected to the negative side conductor on a side of the power supply system with respect to the first core and connects the cooler to the second ground; and a third ground conductor connected between the negative side conductor on the side of the power supply system with respect to the first core or the first ground conductor and a third ground such that the negative side conductor on the side of the power supply system with respect to the first core and the first ground conductor have a same potential as that of the third ground.
