Abstract
A virtual and parallel power extraction method by using time division, comprising an alternating current load (), a load end time-division power extraction control device (), a switch end time-division power extraction control device (), and a switch end power supply load (). The alternating current load () is connected in parallel with the load end time-division power extraction control device (); the switch end time-division power extraction control device () is connected in parallel with the switch end power supply load (); a combination body formed by connecting the alternating current load () with the load end time-division power extraction control device () in parallel and the combination body formed by connecting the switch end time-division power extraction control device () with the switch end power supply load () in parallel are together connected in series in an alternating current circuit. The present invention provides an efficient power extraction method between an electronic switch and a connected load on the premise of having no a neutral line, and particularly solves the problem that the electronic switch is falsely turned off or incompletely turned off for a low-power LED lamp.
