<P>PROBLEM TO BE SOLVED: To provide a power converter which performs a high conversion efficiency with a simple configuration. <P>SOLUTION: A DC/DC converter 2 detects the voltage (input voltage) of a DC power supplied from a photovoltaic cell 1, switches the DC power, supplies the DC power to a transformer 15, detects the voltage (output voltage) of the DC power obtained by rectifying the AC power stepped up by the transformer 15, and controls the on duty of switching elements 33, 34 by a control circuit 46 so that a ratio of the detected values of the input to the output voltage becomes constant. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
