Abstract
This power supply circuit for work machine is provided with a first switch for switching connection and disconnection of a first electrical path provided between a battery and a load which is driven with the power of the battery, and a second switch for switching connection and disconnection of a second electrical path bypassing the first switch. The second switch, when the first switch is switched from a state in which the first electrical path is connected to a state in which the first electrical path is disconnected, places the second electrical path in a connected state for a certain period and then, after the period elapses, switches the state in which the second electrical path is connected to a state in which the second electrical path is disconnected.
