An inverter device includes an inverter circuit, which has switching elements in a bridge connection, a capacitor, which is connected in parallel to the input side of the inverter circuit, a control device, which controls the inverter circuit, a temperature detector, which detects the temperature of the capacitor, a degree-of-deterioration determiner, which determines the degree of deterioration of the capacitor, and a warm-up controller. When the temperature of the capacitor detected by the temperature detector is lower than a prescribed temperature, the warm-up controller controls the switching elements of the inverter circuit to supply a direct current set based on the degree of deterioration and the temperature of the capacitor to the coil of an electric motor connected to the output side of the inverter circuit.

Inverter device

An inverter device includes an inverter circuit, which has switching elements in a bridge connection, a capacitor, which is connected in parallel to the input side of the inverter circuit, a temperature detector, which detects the temperature of the capacitor, a battery charge information acquisition section, which acquires charge information related to a battery connected to the input side of the inverter circuit, and a warm-up controller. When the temperature of the capacitor detected by the temperature detector is lower than a prescribed temperature, the warm-up controller determines a warm-up current based on the battery charge information acquired by the battery charge information acquisition section and the temperature of the capacitor detected by the temperature detector, and controls the switching elements of the inverter circuit to supply the warm-up current to the coil of an electric motor connected to the output side of the inverter circuit.

An exhaust gas processing device () intermittently introduces anode off-gas from a fuel cell (). The exhaust processing device () discharges the anode off-gas after diluting it with dilution gas. The exhaust gas processing device () includes a dilution container () and a partition plate (), which divide the interior of the dilution container () into a first chamber () and a second chamber (). The partition plate () has a clearance (), which connects the first chamber () and the second chamber () to each other. The exhaust gas processing device () includes a discharge portion () provided in the first chamber (), a dilution gas inlet portion () provided in the first chamber (), and an anode off-gas inlet portion () provided in the second chamber ().

An inverter includes a warm-up control section and a switching control section. In a state in which an electric motor is not operating, the warm-up control section controls switching elements of an inverter circuit to perform warm-up control, in which direct currents are supplied to the coils of the respective phases of the electric motor, when the temperature of the capacitor is lower than a prescribed temperature. When a warm-up control is switched to a normal operation control, the switching control section sets initial phases of alternating currents such that the relationship between the values of the alternating currents supplied to the coils of the electric motor in the normal operation control matches with the relationship between the values of the direct currents that have been supplied to the corresponding coils of the electric motor in the warm-up control.
