Abstract
A control method is provided for a power converter configured to generate an output voltage according to a control law controlling a power stage. The method comprises a dual stage identification process for identifying parameters of the power stage. The method includes, in a first stage, identifying at least one parameter of the power stage during ramp up of the power converter and adapting the control law to the identified at least one parameter of said power stage for operating the power converter. The method further includes, in a second stage, determining a response of the power stage; identifying at least one other parameter of the power stage by characterizing the response; and further adapting the control law according to a characteristic of the response.
