<P>PROBLEM TO BE SOLVED: To suppress a voltage change at a voltage dividing point, relating to power conversion equipment. <P>SOLUTION: A controller 4 compares the quantity of charge, which passes from the side of a sub switching circuit to the side of the voltage dividing point, with the quantity of charge, which passes from the side of the voltage dividing point to the side of a main switching circuit, based on the quantity of charge, which passes each of sub switching circuits, in each control cycle. Then, the controller 4 corrects the operation period of switching motion to be short, as to a sub switching circuit where the quantity of charge passing it becomes maximum, based on the comparison results. <P>COPYRIGHT: (C)2010,JPO&INPIT |
