US Patent 9312782 Power converter equipped with semiconductor module

In a power converter, a plurality of AC busbars are electrically connected to an AC load. An insulating support surrounds at least part of a stacked converter unit of semiconductor modules and refrigerant paths. The set of busbars are fixedly mounted on the insulating support. A terminal holder has a mount surface on which one end of each of the plurality of AC busbars is mounted as a terminal. A current sensor has a through-hole and measures a current flowing through at least part of at least one of the plurality of AC busbars. The current sensor is attached to the terminal holder with the at least part of the at least one of the plurality of AC busbars being fitted in the through-hole of the current sensor.
