Abstract: <P>PROBLEM TO BE SOLVED: To provide a direct type AC power conversion device which can reduce rush current.  <P>SOLUTION: A current type converter 1 is controlled by a controller 5 in a continuity state of a switch S1 so that a voltage between a neutral phase input line ACLn, where a resistor R1 is provided, and any of input lines ACLr, ACLs, ACLt is subjected to double voltage rectification and fed as a charge voltage to clamp capacitors Cc1, Cc2. In this way, the charge voltage is fed through the resistor R1 to the clamp capacitors Cc1, Cc2, and thereby a rush current caused to flow to them can be prevented. Then, the both end voltage of the clamp capacitors Cc1, Cc2 in pairs is larger than that of capacitors Cr, Cs in pairs, for example, and thereby the rush current from the capacitors Cr, Cs to the clamp capacitors Cc1, Cc2 can be prevented even if the clamp capacitors Cc1, Cc2 and, for example, the capacitors Cr, Cs are connected electrically at a normal operation time.  <P>COPYRIGHT: (C)2009,JPO&INPIT
