Abstract:
An electronic apparatus characterized by comprising:a power generating means for performing power generation by converting first energy into second energy which is electrical energy; a first power supply means for accumulating the electrical energy obtained by said power generating means; a power supply voltage converting means for converting the voltage of the electrical energy supplied from said first power supply means by a voltage-conversion multiplying factor M (M is a positive real number); a second power supply means, to which the electrical energy accumulated in said first power supply means is transferred through said power supply voltage converting means, for accumulating the transferred electrical energy; a driven means driven by the electrical energy supplied from said first power supply means or said second power supply means; and non-voltage-converting transfer control means for transferring, in the transition from a state in which the electrical energy is being transferred from said first power supply means to said second power supply means through said power supply voltage converting means by a voltage-conversion multiplying factor Mâ€² (Mâ€² is a positive real number except for one) to a state in which said first power supply means and said second power supply means are electrically directly coupled, the electrical energy from said first power supply means to said second power supply means through said power supply voltage converting means by the voltage-conversion multiplying factor M=1 in a non-voltage-converting state, wherein a potential difference between said first power supply means and said second power supply means is less than a predetermined potential difference.
