Abstract
An electric working machine in one aspect of the present disclosure includes a driving device, a controller, a control power source, and an operation state determiner. The control power source includes a first converter and a second converter. The control power source transitions to a first conversion state when the operation state determiner determines that the controller is in a control operation state. The control power source in the first conversion state supplies a first control current to the controller. The control power source transitions to a second conversion state when the operation state determiner determines that the controller is in a low power operation state. The control power source in the second conversion state (i) stops operation of the first converter, and (ii) supplies a second control current to the controller.
