Claim 0:
1. A control device for an isolated converter comprising a switching transistor that selectively applies a voltage to a transformer, the control device comprising:
a comparison module that receives a load percentage of the isolated converter, compares the load percentage with a first preset threshold and a second preset threshold, and outputs a comparison result; and
an adjustment module that receives the comparison result and adjusts a switching frequency of the switching transistor based on the comparison result, wherein when the load percentage is not greater than the first preset threshold, the switching frequency is set to a first frequency to prevent magnetic saturation of the transformer, 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 to make a temperature of the isolated converter not greater than a maximum allowable temperature, wherein the first preset threshold is less than or equal to the second preset threshold, and wherein the first frequency is greater than the second frequency.
