Abstract
A power line communication apparatus includes a drive block including an actuator control circuit and a drive circuit and a communication block. The actuator control circuit generates a control pulse for controlling an actuator, and controls a transition timing of the control pulse during an operation period set within a communication cycle by a communication clock. The drive circuit controls a driving current of the actuator supplied from a DC power source through a power line based on the control pulse in which the transition timing is controlled. The communication block generates the communication clock, and modulates a current flowing through the power line in response to data to be transmitted during a signal transmission period different from the operation period, set within the communication cycle.
