Claim:
1. A power system, comprising: a fixed geometry turbocharger comprising a turbine coupled to a compressor; a second fixed geometry turbocharger comprising a second turbine coupled to a second compressor; a variable geometry (VG) turbocompound turbine positioned downstream of the turbine, but positioned upstream of the second turbine, relative to a direction of a flow of an exhaust gas flowing through the turbine and the second turbine; an electrical generator driven by the VG turbocompound turbine; and a controller, the controller being configured to send a signal to adjust a geometry of the VG turbocompound turbine so as to adjust a boost level being provided by a combination of the fixed geometry turbocharger and the second fixed geometry turbocharger.
