When a high-pressure compressor stage operates in an efficient operating zone defined on a compressor performance to one side of an optimum performance line that is spaced from but generally parallel to a choke limit line, the turbocharger is controlled by closed-loop control of vanes of the high-pressure turbine stage while a by-pass around the high-pressure turbine stage is kept closed. When the high-pressure compressor stage operates in a zone between the optimum performance line and the choke limit line, the vanes of the high-pressure turbine stage are increasingly opened as operation of the high-pressure compressor stage increasingly approaches the choke limit line. When the vanes have been maximally opened and the high-pressure compressor stage has become unable to provide sufficient boost, the high-pressure turbine by-pass is opened to begin routing exhaust flow to a low-pressure turbine that operates a low-pressure compressor stage, thereby avoiding choking of the charge air flow by the high-pressure compressor stage.
