An electric power converter which is provided with: a plurality of power conversion elements; a first control circuit which outputs a first control signal; an electricity storage circuit; a second control circuit which outputs a second control signal in cases when the direct-current power source that supplies electrical power to the first control circuit is not normal; and a drive circuit which outputs drive signals for driving the plurality of power conversion elements. Each of the plurality of power conversion elements is either a power conversion element of the upper arm connected to the high voltage side or a power conversion element of the lower arm connected to the low voltage side. In cases when the voltage of the electricity storage circuit is at a predetermined first voltage value or higher, the second control circuit outputs a second control signal so that all the power conversion elements of the upper arm or all the power conversion elements of the lower arm are turned on and the others are turned off.
