Abstract
A power converter includes a power module allowing supply and cutoff of main current, a driver module controlling supply and cutoff of the main current, a high potential side semiconductor device, and a low potential side semiconductor device. Plural power module side wirings are connected with respective electrodes contained in the high and low potential side semiconductor devices. Plural driver module side wirings are provided on the driver module as wirings connected with the plural corresponding power module side wirings. Conductors are disposed in the vicinity of a plane on which the plural power module side wirings are provided and a plane on which the plural driver module side wirings are provided, and electrically connected to surround magnetic flux generated by current looping at least through a power source transformer, the driver module side wirings, and the power module side wirings.
