Abstract:
A power converter which has a power module allowing supply and cutoff of main current, and a driver module controlling supply and cutoff of the main current allowed by the power module includes: a high potential side semiconductor device which allows supply and cutoff of the main current on the high potential side of the power module; a low potential side semiconductor device which allows supply and cutoff of the main current on the low potential side of the power module, and is connected with the high potential side semiconductor device in series; plural power module side wirings connected with respective electrodes contained in the high potential side semiconductor device and the low potential side semiconductor device, and disposed adjacent to each other substantially on the same plane as the power module in the order of applied potentials with a connection end between the plural power module side wirings and the driver module located along the end of the power module; plural driver module side wirings provided on the driver module as wirings connected with the plural corresponding power module side wirings, and disposed adjacent to each other substantially on the same plane as the driver module in the order corresponding to the positions of the plural power module side wirings in positions along the end of the driver module; a power source transformer as a circuit which converts a signal voltage for controlling the supply and cutoff of the main current by the driver module into voltage applied to a control electrode of the high potential side semiconductor device and a control electrode of the low potential side semiconductor device, plural terminals of the power source transformer in correspondence with the plural driver module side wirings being provided in the order of the positions of the plural corresponding driver module side wirings; and conductors disposed in the vicinity of the plane on which the plural power module side wirings are provided and in the vicinity of the plane on which the plural driver module side wirings are provided, and electrically connected in such positions as to surround magnetic flux generated by current looping at least through the power source transformer, the driver module side wirings, and the power module side wirings.
