Patent ID: 7095220

Claim:
A method of controlling an operation of a switching power converter which includes first and second series connected transistors, each having a conduction control terminal for receiving a conduction control signal, the method comprising: applying a first series of conduction control signals to the control terminal of the first transistor; applying a second series of conduction control signals to the control terminal of the second transistor, wherein the second series of conduction conduction control signals is applied out of phase with respect to the first series conduction control signals, and an edge of a falling transition of the conduction control signal of the first transistor is spaced apart from an edge of a rising transition of the conduction control signal of the second transistor by a first amount of time; measuring a ratio of an input voltage to an output voltage of the series connected transistors operating at the first spacing; changing the spacing to a second amount of time and measuring a ratio of the input voltage to the output voltage for the second spacing.
