Abstract
The electric-power conversion apparatus includes an electric-power conversion circuit having two or more legs in each of which there are provided a positive-polarity switching device, a negative-polarity switching device, and an external connection point at which the positive-polarity switching device and the negative-polarity switching device are connected in series with each other and that is connected with an electric rotating machine, a capacitor connected with a positive electrode and a negative electrode, a voltage sensor for detecting a voltage between the positive electrode and the negative electrode, a temperature sensor for detecting a temperature of the electric-power conversion circuit, and a control unit that on/off-controls the switching devices in the electric-power conversion circuit and that performs protective control in the case where a voltage detected by the voltage sensor is larger than a determination voltage calculated based on a temperature detected by the temperature sensor.
