Power converter and method of entering skip at a fixed output power in a light load condition independent of magnetizing inductance

A method of maintaining a fixed output power during a light load condition in a power converter, comprising:

• providing a semiconductor device;
• reducing a switching frequency of the semiconductor device during the light load condition;
• and
• controlling a pulse width of a drive signal to the semiconductor device to select a current through the semiconductor device corresponding to the switching frequency to maintain the fixed output power of the power converter.

A power converter having a fixed output power during a light load condition, comprising:

• a semiconductor device;
• means for reducing a switching frequency of the semiconductor device during the light load condition;
• and
• means for controlling a pulse width of a drive signal to the semiconductor device to select a current through the semiconductor device corresponding to the switching frequency to maintain the fixed output power of the power converter.
