<p><P>PROBLEM TO BE SOLVED: To improve the power converting efficiency of a current transformer, a power unit, and a sensor system by accurately making the split surfaces of a core used for the transformer, unit, and system coincide with each other. <P>SOLUTION: Each of the current transformer, power unit, and sensor system has a core composed of a magnetic material, a winding wound around the core and composed of a conductor, and a package supporting the core. The core is constituted by splitting the core into two or more portions, and an elastic body, such as the spring, sponge, etc., is arranged between at least one split portion of the core and the package. Consequently, the split surfaces of the core used for the current transformer, power unit, and sensor system can be accurately made to coincide with each other, and the power converting efficiency of the transformer, unit, and system is improved. <P>COPYRIGHT: (C)2004,JPO</p> |
