The present invention provides a power converter having a structure capable of reducing switching noise and insusceptible to switching noise.The power converter comprises a semiconductor device, a driver device, a current sensor, a control device, and a capacitor. The semiconductor device has a plurality of switching elements for converting a direct current to an alternating current, the direct current being supplied from a direct current terminal. The driver device controls an operation of the plurality of switching elements provided in the semiconductor device. The current sensor detects the alternating current. The control device controls an operation of the driver device in accordance with the alternating current that has been detected by the current sensor. The capacitor is connected with the direct current terminal. The driver device and the control device are mounted on the same printed board. The driver device is arranged above the semiconductor device.
