Abstract:
1. A power converter comprising: a first power supply line; a second power supply line applied with a potential lower than said first power supply line; an output end; a power converting section including a first switching element arranged between said output end and said first power supply line, and a power supply section having both ends between which a DC voltage is supported, one end on a low potential side of said ends being connected to said first switching element on said second power supply line side and serving as an operation power supply for outputting a switch signal to said first switching element; a second switching element arranged between said first and second power supply lines; a boot capacitor including one end connected to the second switching element on said first power supply line side and another end electrically connected to the other end of said power supply section, and serving as an operation power supply for outputting a switch signal to said second switching element when charged; and a diode, arranged between the other end of said power supply section and said first power supply line through said boot capacitor, for flowing current only in a direction from said power supply section towards said boot capacitor.
