Claim 3:
4. The bleeder control circuit according to claim 1, wherein the time processing module comprises:
a first storage module configured to receive the first time signal in the previous power frequency half-wave cycle to store as the second time signal;
a first comparison module configured to receive the first time signal and the second time signal in one power frequency half-wave cycle and output a third signal when the first time signal is not equal to the second time signal;
a first processing module configured to receive the third signal and increase the second time signal by a step in a next power frequency half-wave cycle; and
a first timing module configured to receive the bus voltage, the first threshold voltage and the second time signal, and output the second time signal when the rising edge of the bus voltage reaches the first threshold voltage.
