Charger for battery driven vehicle

Abstract

Abstract PURPOSE:To construct a compact battery driven vehicle without exclusively providing a charger such as a rectifier by using as a charger for the vehicle a drive inverter as it is and operating it as a regenerative mode. CONSTITUTION:A DC power of a battery 1 is converted by an inverter 2 into AC in a normal drive state, a switch 3 is closed by a command of a control circuit 7 to drive an induction motor 4. At this time a power source is not connected to a commercial power terminal 6. In the charging state, the switch 3 is opened by the control circuit 7 in the state that the commercial power source is connected to the terminal 6, and transistors of phases U and V are pulse-width modulation controlled to operate the inverter 2 in the regenerative mode.
