<P>PROBLEM TO BE SOLVED: To provide a power converter which can take out the latest information from information successful in writing at a power source resetting time even if a writing failure occurs at a control power supply loss time during writing by writing the information in a nonvolatile memory by a simple circuit configuration. <P>SOLUTION: The power converter is electrically connected to a solar cell to convert dc power generated from the solar cell into ac power. The power converter electrically connects the solar cell to a load system or a commercial power system to perform linkage operation. The power converter includes a storage unit made of a nonvolatile memory for storing an output voltage, the output current and the lapse time information of the solar cell, a plurality of areas in the storage unit which sequentially stores the output voltage, the output current and the lapse time information of the solar cell at predetermined time intervals in each area. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
