Patent ID: 8736203

Claim:
An inverter/charger integrated device comprising: a three-phase motor; a first rectifying unit configured to rectify three-phase AC power for high-speed charging of a battery; a second rectifying unit configured to rectify single-phase AC power for low-speed charging of the battery; a switch unit comprising at least one switch and configured to selectively connect the first or second rectifying unit to the three-phase motor according to a charging mode; a rectifier/inverter integrated unit configured to be selectively connected to the first or second rectifying unit in order to charge the battery; a low-voltage rectifying unit configured to decrease a DC voltage output by the rectifier/inverter unit in order to output low-voltage DC power; and a control unit configured to control the switch unit to: selectively disconnect the three-phase motor from the first and second rectifying units; and selectively connect the first or second rectifying unit to the three-phase motor according to the charging mode.
