<p><P>PROBLEM TO BE SOLVED: To provide a power supply system that is reduced in size by suppressing the generation of the heat of a circuit component of a power converter, and has a regeneration function. <P>SOLUTION: A control value of an output current of the power converter 16 when both-end voltages of a capacitor 15 are higher than both-end voltages of a battery 17 is set as a first current value, a control value when both the both-end voltage are almost equal is set as a second current value, the first current value is set smaller than the second current value. By this arrangement, since the heat is hardly generated when the both-end voltages of the capacitor 15 and the both-end voltages of the battery 17 are almost equal, a control value (the second current value) of an output current is set as the largest current that a load 18 consumes, and when the both-end voltages of the capacitor 15 are higher than the both-end voltages of the battery 17, a control value (the first current value) of the output current is made to be smaller than the second current value, thus suppressing the generation of the heat to reduce a heat dissipation component in size, and enabling the power supply system to be constituted small in size as a whole. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
