ABSTRACT:
Disclosed is a method of controlling an operation of a switching power converter which includes a first and second series connected transistors. Each of the transistors includes a conduction control terminal for receiving a conduction control signal. A first series of conduction control signals is applied to the control terminal of the first transistor and a second series of conduction control signals is applied to the control terminal of the second transistor, with the second series of conduction control signals being applied out of phase with respect to the first series of conduction control signals. A ratio of an input voltage to an output voltage for the series connected transistors is measured for a first spacing between an edge of a falling transition of the conduction control signal for the first transistor and an edge of a rising transition of the conduction control signal for the second transistor. The operation of the switching power converter is changed by providing a spacing having a second amount of time and the ratio of the input voltage to the output voltage for the second spacing is measured.
