摘要

本发明关于一种适用于单线式电力载波控制系统及其方法。此适用于单线式电力载波控制方法包括：接收由电源线送来的一交流电压，其中，交流电压的每一周期系由一正半波以及一负半波构成之一弦波交流电讯号；根据所欲传送到负载电路的一数位资料，调整上述弦波交流电讯号的正半波以及负半波，包括：切除上述弦波交流电讯号的正半波与负半波的波形，获得一相位切除讯号，其中，当数位资料为第一逻辑时，上述相位切除讯号的正半波等于上述相位切除讯号的负半波；当数位资料为第二逻辑时，上述相位切除讯号的正半波不等于上述相位切除讯号的负半波。; adjusting the positive half-wave and the negative half-wave of the sinusoidal AC signal according to a digital data to be transmit to a load circuit, which including: removing a first component of the positive half-wave of the sinusoidal AC signal and a second component of the negative half-wave of the sinusoidal AC signal to obtain a phase cutting signal, wherein the positive half-wave of the phase cutting signal is equal to the negative half-wave of the phase cutting signal when the digital data is a first logic, and the positive half-wave of the phase cutting signal is not equal to the negative half-wave of the phase cutting signal when the digital data is a second logic.
