Claim Text:
1. A power converter, comprising: a plurality of input ends; a first DC power supply line; a second DC power supply line applied with a potential lower than that of said first DC power supply line; a current-source converter including: a diode provided between said first and second DC power supply lines with an anode thereof directed toward said first DC power supply line; a capacitor provided in series with said diode between said first and second DC power supply lines, wherein a potential of said first DC power supply line side of said capacitor is higher than that of said second DC power supply line side of said capacitor; a first resistor connected in series with said capacitor and said diode between said first and second DC power supply lines; a second resistor provided in a series path linking at least one of said plurality of input ends and said capacitor; and a first switch selecting conduction/non-conduction between said at least one of said plurality of input ends and said capacitor via said second resistor, wherein said power converter is not provided with another capacitor one end of which is directly connected to said first DC power supply line and the other end of which is directly connected to said second DC power supply line, and wherein said first resistor has a resistance value lower than that of said second resistor.
