Claim 2:
3. The bleeder control circuit according to claim 1, wherein the timing module comprises:
a first comparator configured to receive the bus voltage and the first threshold voltage and output a first signal when detecting that the rising edge of the bus voltage reaches the first threshold voltage during each power frequency half-wave cycle;
a second comparator configured to receive the bus voltage and the second threshold voltage and output a second signal when detecting that the falling edge of the bus voltage reaches the second threshold voltage during each power frequency half-wave cycle; and
a detection module configured to receive the first signal and the second signal, detect the time between the first signal and the second signal during each power frequency half-wave cycle, and generate the first time signal.
