Document Type and Number:

WIPO Patent Application WO/2018/216850

Kind Code:

A1

Abstract:

A power conversion device according to an embodiment of the present invention comprises: a DC link capacitor charged with a direct-current power supplied from a power supply part; a fuse part, connected to an output terminal of the power supply part, for breaking a current which is output from or supplied to the power supply part and has a first breaking magnitude or greater; a relay part which comprises a first relay for connecting a positive terminal of the fuse part to a positive terminal of the DC link capacitor and a second relay for connecting a negative terminal of the fuse part to a negative terminal of the DC link capacitor; an initial charge part, connected to the first relay in parallel, for charging the DC link capacitor by using direct-current power supplied from the power supply part; and a power conversion part for converting the direct-current power supplied from the power supply part into alternating-current power when the DC link capacitor has been charged and supplying the alternating-current power to a load terminal.
