Classification: CPC H  Y | IPC H

Claim 4:
5. The bleeder control circuit according to claim 1, wherein the time processing module comprises:
a second 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 second comparison module configured to receive the first time signal and the second time signal in the same one power frequency half-wave cycle and compare the first time signal with the second time signal to obtain a third time signal;
a second processing module configured to receive the third time signal and compare the third time signal with a first predetermined time and increase the second time signal by a step in a next power frequency half-wave cycle when the third time signal is smaller than the first predetermined time and greater than a second predetermined time or decrease the second time signal by a step in the next power frequency half-wave cycle when the third time signal is greater than the first predetermined time; and
a second 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.
