<p><P>PROBLEM TO BE SOLVED: To detect the polyphase current more precisely by using surface mounted current sensors. <P>SOLUTION: Current paths to be detected 1U, 1V, and 1W are aligned in a plane, and current paths other than the 1U, 1V, 1W are placed in a reverse direction, in fact are placed perpendicularly to them. The magnetic flux of each flowing current in the current paths 1U, 1V, 1W is detected by each of surface mounted current sensors 11, 12, 13. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
