Abstract:
The invention discloses a method for controlling a bleeder connected to a phase-cut dimmer and a circuit connected to a phase-cut dimmer. The method includes detecting an input voltage of the bleeder to obtain a detection voltage, and comparing the detection voltage and a preset reference voltage, wherein during a first time period, the detection voltage is less than the preset reference voltage, a start point of the first time period is a first moment, and an end point of the first time period is a second moment; delaying a first preset duration on the basis of the second moment to turn off the bleeder; and advancing a second preset duration on the basis of the first moment to turn on the bleeder.
