Classification: CPC H  Y | IPC H

Claim 9:
10. A control method for a conversion device, comprising:
receiving an input voltage from a primary side circuit and outputting an output voltage to a load through a secondary side circuit; and
controlling a peak value of a current of a primary side switch of the primary side circuit to be limited in a band range by a control circuit;
adjusting a blanking time of the primary side switch when the peak value of the current of the primary side switch is beyond the band range; wherein,
decreasing the blanking time by the control circuit when the peak value of the current of the primary side switch is larger than an upper limit value of the band range; and
increasing the blanking time by the control circuit when the peak value of the current of the primary side switch is smaller than a lower limit value of the band range.
