摘要： According to an aspect of the present invention, a drive control apparatus is provided. The drive control apparatus receives a transmission signal, where a plurality of control signals is superimposed on a power transmission voltage, through an electric wire and drives and controls a device to be controlled. A detection frequency is set in the drive control apparatus. One of the plurality of control signals is a control signal for controlling the device to be controlled. The frequency of the control signal is close to the detection frequency. The drive control apparatus includes a drive voltage generator which generates a first drive voltage from the power transmission voltage of the transmission signal and drives the device to be controlled, a detection current generator which generates a detection current whose frequency is the detection frequency, a magnetic element through which the detection current flows and which generates an output corresponding to a result of multiplication of the detection current and a current flowing through the electric wire, and a signal processor which detects the control signal for controlling the device to be controlled from the output from the magnetic element and controls the device to be controlled based on the control signal.

摘要： There is a limit on the miniaturization of electric leakage detecting apparatuses including a ring-shaped magnetic material. Any thicker electric wires increase the size of the ring-shaped magnetic material. Additionally, it is difficult to place the ring-shaped magnetic material around the electric wires that have already been placed. In light of the foregoing, an electric leakage apparatus is provided. The electric leakage detecting apparatus is to be installed on a pair of power source lines connecting a power source and a load, and includes: a pair of holders configured to hold the power source lines, respectively; a fixing means configured to fix the holders at a predetermined interval; a pair of magnetic elements each placed on each of the holders while being parallel to the power source lines; a detecting means configured to detect a difference between magneto-resistance effects of the magnetic elements; and a driving means configured to feed a drive current to the magnetic elements.
