Abstract:
1. A method, comprising: acquiring a form of an output pulse at the output of a power bridge in response to a bridge control input under each of a plurality of power bridge output current conditions for the power bridge; processing the output pulse form for each power bridge output current condition in order to estimate power bridge non idealities relating to errors in pulse area for the output pulse; storing the power bridge output current condition and associated estimated power bridge non idealities; processing an input signal through a model of said power bridge in order to estimate a power bridge output current in response to that input signal; using the estimated power bridge output current to retrieve from storage power bridge non idealities at the power bridge output current condition corresponding to the estimated power bridge output current; and regulating edge timing of a power bridge control signal for power bridge switch control in response to the retrieved power bridge non idealities so as to correct for errors in pulse area of the output pulse.
