A supercharging system (10) for an engine includes an air pump (12), an electrical machine (14), an engine-connected input member (15) and a variable-ratio power transmission mechanism (16). The power transmission mechanism (16) includes a sun member (18) operatively connected to one of the air pump (12), the electrical machine (14) and the input member (15). At least one planet member (20) is drivingly interfaced with the sun member (18) and rotatably carried by a carrier (22) operatively connected to another one of the air pump (12), the electrical machine (14) and the input member (15). An annulus (24) is drivingly interfaced with the at least one planet member (20) and operatively connected to the other one of the air pump (12), the electrical machine (14) and the input member (15). The supercharging system (10) also includes a brake (32) configured to selectively inhibit rotation of at least one of the sun member (18), the carrier (22), and the annulus (24). |
