POWER CONVERSION APPARATUS |
摘要 |
A power conversion apparatus includes a power-conversion circuit unit that includes at least two voltage-type bridge circuits of an upper and lower arm configuration including switching elements connected in series, each of the switching elements including a transistor and a free wheel diode connected to the transistor in inverse parallel. Each of the voltage-type bridge circuits is configured to include, as the free wheel diodes: a SiC-SBD (SiC-Schottky-Barrier Diodes) in both upper and lower arms; a SiC-SBD only in the upper arm; a SiC-SBD only in the lower arm; or a diode other than the SiC-SBD in both the upper and lower arms; and the power-conversion circuit unit is configured by combining at least two configurations among the four configurations for the voltage-type bridge circuits. |
