<P>PROBLEM TO BE SOLVED: To provide a voltage control circuit capable of stably supplying electric power while suppressing loss of electric power, and to provide an electrical device that uses the voltage control circuit. <P>SOLUTION: The voltage control circuit includes a power generation part 2 which generates electric power by self power generation, a main circuit part 3 connected to the power generation part 2, an energy accumulation part 5 connected to the power generation part 2 and the main circuit part 3, and a voltage limiter part 6 connected among the energy accumulating part 5, the power generation part 2, and the main circuit part 3. When the voltage of the main circuit part 3 exceeds a set value, the electric power corresponding to the exceeding voltage in the power generated at the power generation part 2 is supplied to the energy accumulating part 5 through the voltage limiter part 6 and accumulated. When the voltage of the main circuit part 3 drops below the set value, the electric power accumulated in the energy accumulating part 5 is supplied to the main circuit part 3 through the voltage limiter part 6. <P>COPYRIGHT: (C)2012,JPO&INPIT |
