FIELD: electrical engineering.
SUBSTANCE: invention relates to electrical engineering, in particular to an electric working machine. An electric working machine in one aspect of the present invention includes a drive device, a controller, a control power source and a means of determining the operating state. The control power supply includes the first converter and the second converter. The control power supply enters the first conversion state when the means of determining the operating state determines that the controller is in the control operating state. The control power supply in the first conversion state supplies the first control current to the controller. The control power supply enters the second conversion state when the operating state detection tool determines that the controller is in a low-power operating state. The control power supply in the second conversion state (i) stops the operation of the first converter and (ii) supplies the second control current to the controller.
EFFECT: reducing energy consumption in an electric working machine in the standby mode.
