<P>PROBLEM TO BE SOLVED: To provide a Hall IC current sensor which is inexpensive and miniaturized in comparison with a high current sensor and simplifying an assembling property of a vehicle power converter. <P>SOLUTION: The Hall IC current sensor of the vehicle power converter has a bus bar connected to a power supply and supplying power to the vehicle power converter, the Hall IC for measuring generated magnetic flux when the bus bar carries a current and outputting an electrical signal according to magnetic flux density and detecting a current carried in the bus bar, and a control board formed with a control circuit for controlling the vehicle power converter in response to an output from the hall IC. The sensor is also provided with a Hall IC holder 3 for holding the Hall IC 2 and fixed to the bus bar 1, and a through-hole 4a formed at the control board 4 and into which a lead terminal 2a of the Hall IC 2 penetrates. The lead terminal 2a penetrating into the through-hole 4a is connected to the control circuit by solder bonding. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
