Claim 9:
10. A control method for an isolated converter comprising a switching transistor that selectively applies a voltage to a transformer, the method comprising:
comparing a load percentage of the isolated converter with a first preset threshold and a second preset threshold; and
adjusting a switching frequency of a switching transistor of the isolated converter based on the comparison, wherein when the load percentage is not greater than the first preset threshold, the switching frequency is set to a first frequency value to prevent magnetic saturation of a transformer of the isolated converter, wherein when the load percentage is greater than the second preset threshold and in a stable state, the switching frequency is set to a second frequency value to make the temperature of the isolated converter not greater than the maximum allowable temperature, wherein the first preset threshold is less than or equal to the second preset threshold, and wherein the first frequency value is greater than the second frequency value.
