Power line communication control system adapted for single-wire and method thereof
A power line communication control system adapted for single-wire and method thereof are provided in the present invention. The power line communication control method adapted for single-wire includes: receiving a AC voltage from a AC power wire, wherein each period of the AC voltage includes a positive half cycle and a negative half cycle to form a sinusoidal AC signal; and adjusting the positive half cycle and the negative half cycle of the sinusoidal AC signal according to a digital data to be transmit to a load circuit. The step of adjusting the positive half cycle and the negative half cycle of the sinusoidal AC signal includes removing a first component of the positive half cycle of the sinusoidal AC signal and a second component of the negative half cycle of the sinusoidal AC signal to obtain a phase cutting signal. When the digital data is a first logic, the positive half cycle of the phase cutting signal is equal to the negative half cycle of the phase cutting signal. When the digital data is a second logic, the positive half cycle of the phase cutting signal is not equal to the negative half cycle of the phase cutting signal.
