<P>PROBLEM TO BE SOLVED: To obtain a power supply system capable of preventing generation of an excessive regenerative power even if a main switch is turned off during traveling without requiring a large member such as a discharge resistor in an electric two-wheeled vehicle. <P>SOLUTION: The system has a sub-battery 5, a power supply line 22, a motor driving portion 2 which controls the output and power generation of a motor 8, a controller 1 which is supplied with power through the power supply line 22 to control the motor driving portion 2, a switch control line 21 connected by branching to the power supply line 22, a relay switch S2 which is maintained in an on-state according to an instruction from the controller 1, when the main switch S1 connected to the switch control line 21 is controlled once to an on-state, and a self-holding power supply portion 7 which supplies power from the power supply line 22 to the controller 1. The controller 1 drives the motor driving portion 2 so as to reduce a power generation amount, when the switch S1 is an off-state and the motor 8 functions as a generator. <P>COPYRIGHT: (C)2012,JPO&INPIT |
