PURPOSE:To provide an inductive load drive apparatus capable of reducing unnecessary radiation and the generation of induced noise and of securing good rising of a load current without increasing its power supply circuit and costs. CONSTITUTION:In an inductive load drive apparatus for driving an inductive load L by controlling a mean voltage or a mean current applied to the inductive load through the switching of a power supply applied to the inductive load L at a predetermined duty ratio, a reactor L1 is connected in series to the inductive load L, and voltage vibration and ripples in a load current generated at both the ends of the inductive load L are reduced and the generation of unnecessary radiation and inductive noise from signal lines to the inductive load L is decreased. |
