PURPOSE:To exactly obtain the mutual inductance in case when the lattice circuit has been equivalently converted to the bridge T type circuit, by forming the mutual inductance separately from the self-inductance. CONSTITUTION:Although the lattice circuit (c) is equivalent to the bridge T type circuits (d), (e), it has a negative inductance in case of m>1, and therefore, it can be converted to only the circuit (e) for using the mutual inductance. Therefore, it is adjusted so that the mutual inductance becomes M=(1-m<2>) L0/2m, by tightly coupling two windings in reverse to each other to the coil 6, and winding them so that the coupling coefficient is approximately 1. As a result, the self-inductance becomes L3=L4=¦M¦. Subsequently, when the coils 5, 6 are formed so that the inductance becomes L1=L2=(1+m<2>) L0/2m-¦M¦, the mutual inductance and the self-inductance of the circuit (e) are obtained. In this way, the mutual inductance is obtained exactly. |
