ABSTRACT:
In a power drive unit having power modules (three-phase inverter circuits) connected to a control circuit board, bus bars extending from the power modules and a current sensor each installed near the bus bars and including a sensing element that detects currents outputted from the bus bars, there are provided a sensor board on which the sensing element is mounted, and lead pins each connecting the sensor board to the control circuit board and having a bowed shape whose one end is connected to the sensor board and other end once extends away from the circuit board and then turns back toward the circuit board. With this, the circuit board and current sensors can be connected through the lead pins without increasing the distance therebetween and stress produced in the lead pins can be alleviated, thereby enabling the unit to be minimized in size and utilized in a harsh service environment.
