Beschreibung
Zusammenfassung:	A power conversion device includes a first inverter, a second inverter, first and second controller to control the first and second inverters, and a driving circuit to apply a control signal to turn on the low side switch elements of the first inverter when a fault occurs on the first inverter side, and apply a control signal to turn on the low side switch elements of the second inverter when a fault occurs on the second inverter side. The first power voltage generated on the first inverter side is supplied to the driving circuit when a fault occurs on the second inverter side, and the second power voltage generated on the second inverter side is supplied to the driving circuit when a fault occurs on the first inverter side.
