1. A driving circuit for power supply line carrier, applied to driving a load operating, comprising: a control module, a switching module and a half-voltage generating module,
wherein the control module connects to the switching module, the control module is applied to outputting a control signal to the switching module, so as to control the switching module to be turned on or off,
wherein the switching module connects with a power supply line, the half-voltage generating module and the load respectively, the switching module is applied to, when being turned on, charging the half-voltage generating module with a power supply voltage provided by the power supply line and outputting the power supply voltage to the load and to terminate the power supply voltage to the half-voltage generating module when being turned off, and;
wherein the half-voltage generating module further connects to the load, the half-voltage generating module is applied to providing a supply voltage to the load when the switching module is turned off, the load demodulates the control signal according to the power supply voltage and the supply voltage before controlling a state thereof according to the control signal, wherein the half-voltage generating module comprises: a first energy storage unit, a second energy storage unit and a charging-and-discharging control, wherein the first energy storage unit connects to the switching module, the charging-and-discharging control unit and the load, respectively, wherein the second energy storage unit connects to the charging-and-discharging control unit and the load, respectively, and wherein the charging-and-discharging control unit is applied to controlling the first energy storage unit and the second energy storage unit to be charged in series, and applied to controlling the first energy storage unit and the second energy storage unit to be discharged in parallel.
