Abstract
A converter includes a plurality of switching element units corresponding to respective phases of a multiphase AC voltage, each of the switching element units including a switching element (upper arm-side switching element) on an upper arm side and a switching element (lower arm-side switching element) on a lower arm side, the upper arm-side switching element and the lower arm-side switching element being connected in series to each other. In a case that a determination unit determines that a short-circuit failure has occurred in any of the plurality of switching elements provided in the converter, a control unit can perform first control of placing, in an ON-state, all the switching elements provided in the converter.
Claims5
An electrical power supply system comprising:
- a converter including a plurality of switching elements and configured to convert a multiphase alternating current voltage output from a generator into a direct current voltage;
- and
- one or more processors that execute computer-executable instructions stored in a memory,
- wherein the converter includes a plurality of switching element units corresponding to respective phases of the multiphase alternating current voltage, each of the switching element units including an upper arm-side switching element that is one of the switching elements on an upper arm side, and a lower arm-side switching element that is one of the switching elements on a lower arm side, the upper arm-side switching element and the lower arm-side switching element being connected in series to each other, and
- the one or more processors execute the computer-executable instructions to cause the electrical power supply system to, in a case that it is determined that a short-circuit failure has occurred in any of the plurality of switching elements provided in the converter, perform first control of placing, in an ON-state, all of the switching elements provided in the converter.
