Abstract:
A power conversion device that includes an inverter circuit in which arms are connected in parallel to each other between a DC positive terminal and a DC negative terminal in accordance with a number of phases of alternating currents of the plurality of phases, the arms for respective phases each including two switch sections that are connected in series and to be brought into conduction in an on state and out of conduction in an off state, and a connection point between the two switch sections of each of the arms is set as an AC input or output point of each phase; and a controller that outputs switching control signals for performing switching control on the switch sections.

Claim (Index 9):
A power conversion device that converts electric power between DC power and AC power of a plurality of phases, the power conversion device comprising:\n an inverter circuit in which arms are connected in parallel to each other between a DC positive terminal and a DC negative terminal in accordance with a number of phases of alternating currents of the plurality of phases, the arms for respective phases each including two switch sections that are connected in series and to be brought into conduction in an on state and out of conduction in an off state, and a connection point between the two switch sections of each of the arms is set as an AC input or output point of each phase; and a controller that outputs switching control signals for performing switching control on the switch sections, wherein\n each of the switch sections is a parallel circuit of a first switching element and a second switching element that is shorter in a transition time between the off state and the on state than the first switching element, \n in each of the switch sections, a first control signal line connecting a control terminal of the first switching element to the controller and a second control signal line connecting a control terminal of the second switching element to the controller are provided independently of each other, \n the controller independently outputs a first switching control signal to be output to the first control signal line, and a second switching control signal that is a signal different from the first switching control signal and to be output to the second control signal line, and \n the first switching control signal and the second switching control signal are signals for switching, when the first switching element and the second switching element are turned on from the off state to the on state, the first switching element and the second switching element so that a timing when the first switching element is turned on is different from a timing when the second switching element is turned on.
