Patent ID: 7652454

Claim:
An electronic equipment having a boost DC-DC converter, comprising: a boost DC-DC converter configured to convert an electric power received from a power generation device into a boosted electric power, to output the boosted electric power, and to output a first boosted electric power signal, the boost DC-DC converter comprising; a first rectifying means for rectifying the boosted electric power to obtain the first boosted electric power; a second rectifying means for rectifying the boosted electric power into a second boosted electric power; an electric power storage device configured to receive and be charged by the first boosted electric power; and a reverse-current preventing circuit in a charging path through which the first boosted electric power is supplied to the electric power storage device, the reverse-current preventing circuit comprising: a voltage detection circuit for monitoring a voltage of the second boosted electric power; and a switching device controlled by the voltage detection circuit; wherein the boost DC-DC converter uses the second boosted electric power as a power supply.
