Abstract
An arc preventing circuit is disposed between a DC/DC converter and a battery (of 36 volts or 12 volts). In the arc preventing circuit , when the DC/DC converter and the battery are to be connected to each other, the connection is performed via a circuit having a resistor R , and then switched to that in which the connection is performed via a circuit not having the resistor R . When the DC/DC converter and the battery are to be disconnected from each other, the charging voltage of a capacitor C of the DC/DC converter is discharged. According to the configuration, arc generation can be prevented from occurring during works of mounting and dismounting the DC/DC converter.
