More specifically, the control unit 16 determines that an overcurrent state exists if the detection value of the detection unit 15 is equal to or less than the threshold value when the switch 31A is in the on state. The control unit 16 determines that an overcurrent state does not exist if the detection value of the detection unit 15 is not equal to or less than the threshold value when the switch 31A is in the on state.

- the operation unit 41 is, for example, an operation member for adjusting the temperature of a heater (load 3).
- the duty ratio that is set is switched by switching the position of the operation member.
- control unit 16 sets a high stage duty ratio when the outside temperature of the vehicle 1 is low. As a result, when the outside temperature of the vehicle 1 is low, the current supplied to the load 3 increases, and the temperature of the heater (load 3) increases. Also, the control unit 16 sets a low stage duty ratio when the outside temperature of the vehicle 1 is high. As a result, when the outside temperature of the vehicle 1 is high, the current supplied to the load 3 decreases, and the temperature of the heater (load 3) decreases.
- the control unit 16 sets a high duty ratio. This increases the current supplied to the load 3, and the temperature of the heater (load 3) increases.
- the control unit 16 sets a low duty ratio. This decreases the current supplied to the load 3, and the temperature of the heater (load 3) decreases.
- the control unit 16 sets the duty ratio when a start condition is satisfied.
- the start condition may be that the start switch of the vehicle 1 is switched to the on state, that a start operation is performed by the user, or other conditions.
- the control unit 16 sets the duty ratio based on, for example, the outside air temperature of the vehicle 1 or the position of an operating member when the start condition is satisfied. Then, the control unit 16 performs duty control of the switch 31 with the set duty ratio.
- the control unit 16 performs duty control for all the switches 31 by synchronizing the on/off timing of the switches 31.
- the control unit 16 determines whether or not an overcurrent state exists during duty control. If the control unit 16 determines that an overcurrent state exists, it stops duty control and switches all switches 31 to the off state.
- the control unit 16 also determines whether or not a termination condition is met during duty control.
- the termination condition may be that the start switch of the vehicle 1 is switched to the OFF state, that a termination operation is performed by the user, or other conditions.
- the control unit 16 ends the duty control and switches all switches 31 to the OFF state.
- the power supply device 10 can adjust the current supplied to the first connection portion 12 by the circuit unit 13 and supply the current to the multiple loads 3. Moreover, since the number of circuit units 13 is smaller than the number of conductive paths 11 connected to each load 3, the number of switches 31 included in the circuit units 13 can also be smaller than the number of conductive paths 11. Therefore, the power supply device 10 can easily reduce the number of switches 31 in a configuration in which power is supplied to the multiple loads 3.
- the power supply device 10 can set the duty ratio in stages.
- the power supply device 10 can set the duty ratio in as many stages as there are loads 3.
- the power supply device 10 can increase the total current value supplied to the multiple loads 3 in proportion to the stages of the duty ratio.
- the power supply device 10 makes it easy to prevent current from concentrating in some circuit sections 13 because the on/off timing of each switch 31 is synchronized.
- the power supply device 10 only needs to provide the detection unit 15 used to determine an overcurrent state in the circuit unit 13A out of the multiple circuit units 13, making it easy to reduce the number of detection units 15.
- the power supply device 10 can set the duty ratio by reflecting at least one of the outside temperature of the vehicle 1 and the switching operation by the operation unit 41.
- the power supply device 10 makes it easy to standardize the performance of the switches 31 in each circuit section 13.
- the power supply device 10 can adjust the current supplied to multiple loads 3 of the same type.
- the number of duty cycle stages does not have to be the same as the number of conductive paths, nor does it have to be the same as the number of loads.
- the on/off timing of each switch does not have to be synchronized.
- the detection unit detects the voltage value of the circuit unit, but it may also be configured to detect the current flowing through the circuit unit.
- the detection unit may be, for example, a known current sensor.
- the control unit may determine that an overcurrent state has occurred when the detection value (the value of the current flowing through the circuit unit) exceeds a threshold current.
