Abstract
An electric power converter includes a plurality of switch pairs respectively corresponding to a plurality of phases and each consisting of an upper-arm switch and a lower-arm switch. Each of the lower-arm switches of the switch pairs has a first terminal, a second terminal and a gate. The electric power converter further includes: a voltage generation circuit having its positive electrode side connected to the second terminal of only one of the lower-arm switches of the switch pairs; a negative-electrode-side electrical path connected to a negative electrode side of the voltage generation circuit; and at least one capacitor having a first end connected to the second terminal of one of the remainder of the lower-arm switches of the switch pairs, which is not connected with the voltage generation circuit, and a second end connected to the negative-electrode-side electrical path.
