Abstract
A power source circuit includes a first converter, a second converter, a switch and a controller. The switch is configured to switch between a first state and a second state, in which in the first state, a first voltage is not supplied to the second converter whereas in the second state, the first voltage is supplied to the second converter. The controller controls the switch to change the first state to the second state in response to detection of the change in a first current flowing in a first load. The second converter is configured to convert a battery voltage of a battery to a second voltage lower than the battery voltage when the switch switches to the first state and convert the first voltage to the second voltage lower than the first voltage when the switch switches to the second state.
